KVM: x86: report sev_pin_memory errors with PTR_ERR
Callers of sev_pin_memory() treat
NULL differently:
sev_launch_secret()/svm_register_enc_region() return -ENOMEM
sev_dbg_crypt() returns -EFAULT.
Switching to ERR_PTR() preserves the error and enables cleaner reporting of
different kinds of failures.
