crypto: ccp - allow callers to use HV-Fixed page API when SEV is disabled

Browse source

commit 8168a7b72b upstream.

When SEV is disabled, the HV-Fixed page allocation call fails, which in
turn causes SFS initialization to fail.

Fix the HV-Fixed API so callers (for example, SFS) can use it even when
SEV is disabled by performing normal page allocation and freeing.
