[PATCH] Pass mutex member to pthread_mutex_unlock in __libc_lock_unlock_recursive

[Siddhesh Poyarekar]

Hi,

Currently, the definition of macro __libc_lock_unlock_recursive passes
the __libc_lock_recursive_t to pthread_mutex_unlock instead of the
member mutex, which looks like a typo.  The patch below fixes this.  I
am working on a change that uses this macro and have verified that the
build warning resulting from this was fixed.

Also verified on x86_64 that there are no regressions in the
testsuite.  OK to commit?
