userfaultfd: selftest: don't error out if pthread_mutex_t isn't identical
On ppc big endian this check fails, the mutex doesn't necessarily need to be identical for all pages after pthread_mutex_lock/unlock cycles. The count verification (outside of the pthread_mutex_t structure) suffices and that is retained.
