efi: pstore: Drop efivar lock when efi_pstore_open() returns with an error
If kzalloc fails, the function returns -ENOMEM without calling
efivar_unlock(). Since open() returned an error, the calling site
in pstore_get_backend_records() won't call the close() function, so
the lock is never released. Thus drop the lock in case of errors here.
