Ashish Kalra d0e63feca3 crypto: ccp - allow callers to use HV-Fixed page API when SEV is disabled 
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.

Fixes: e09701dcdd ("crypto: ccp - Add new HV-Fixed page allocation/free API")
