[patch] proc_mutex_flock_child_init() should close the file

[Gregory (Grisha) Trubetskoy]

In proc_mutex_flock_child_init(), there is no reason to keep the inherited
file descriptor open, it results in unnecessary open files. Unless I'm
missing something it's ok to close it first thing in flock_child_init().
I've tested this on FreeBSD 4.8.
