Modified Files:
        src/lib/libpthread: pthread_rwlock.c

Log Message:
pthread__rwlock_spin - clarify the test.

It's more pedantically correct to check RW_WRITE_LOCKED before
obtaining the thread id of the owner.  And since there must be an
owner annotate the guard NULL check as unlinkely.

No functional change intended.  Ok ad@.
