x_attrib: fix a memory leak 

The X509_NAME object needs to be free'd even if printing it fails.

Introduced in be5adfd6e3 ("Support subjectDirectoryAttributes and
associatedInformation exts", 2024-06-18), but subsequently moved in
7bcfb41489 ("ossl_print_attribute_value(): use a sequence value only if
type is a sequence", 2024-08-05).
