Clang static checker (scan-build) warning:
block/sed-opal.c:line 317, column 3
Value stored to 'ret' is never read.
Fix this problem by returning the error code when keyring_search() failed.
Otherwise, 'key' will have a wrong value when 'kerf' stores the error code.
Fixes: 3bfeb6125664 ("block: sed-opal: keyring support for SED keys")
