Amit Shah 3401f63e72 crypto: ccp - do not request interrupt on cmd completion when irqs disabled
While sending a command to the PSP, we always requested an interrupt
from the PSP after command completion.  This worked for most cases.  For
the special case of irqs being disabled -- e.g. when running within
crashdump or kexec contexts, we should not set the SEV_CMDRESP_IOC flag,
so the PSP knows to not attempt interrupt delivery.

Fixes: 8ef979584e ("crypto: ccp: Add panic notifier for SEV/SNP firmware shutdown on kdump")
