net: keep track and avoid access of skb containing dma-buf pages.

Add checks through the network stack to avoid kmap()ing content
of the frags of devmem skbs.

Technically, whether or not data can be coalesced is a matter of
individual frag pages more than of the skb. An skb can combine
regular pages and dmabuf pages in principle, but in this current
implementation the skb->devmem flag either indicates that _all_ the
pages are devmem pages or none of them are. In the future skbs with
mixed page types can be added.

virt: sev-guest: self-throttle guest request retries

When throttled, the driver will reschedule itself and then try
again after sleeping half its ratelimit time to avoid a big wait queue.
The ioctl may block indefinitely, but that has always been the case
when deferring these requests to the host.

crypto: ccp - Name -1 return value as SEV_RET_NO_FW_CALL

The PSP can return a "firmware error" code of -1 in circumstances where
the PSP is not actually called. To make this protocol unambiguous, the
value is named SEV_RET_NO_FW_CALL.

virt/coco/sev-guest: Add throttling awareness

The host is permitted and encouraged to throttle guest requests to the
AMD-SP since it is a shared resource across all VMs. Without
throttling-awareness, the host returning an error will immediately lock
out access to the VMPCK, which makes the VM less useful as it can't
attest itself. Since throttling is expected to be a common occurrence, a
cooperative host can return a VMM error code that the request was
throttled.

The driver interprets the upper 32 bits of exitinfo2 as a VMM error code.
For safety, since the encryption algorithm in GHCBv2 is AES_GCM, control
must remain in the kernel to complete the request with the current
sequence number. Returning without finishing the request allows the the
guest to make another request but with different message contents. This
is IV reuse, and breaks cryptographic protections.

A guest request may not make it to the AMD-SP before the host returns to
the guest, so the err local variable in handle_guest_request must be
initialized the same way fw_err is. snp_issue_guest_request similarly
should set fw_err whether or not the value is non-zero, in order to
appropriately clear the error value when zero.
