autofs-5.1.7 - add missing free in handle_mounts()

From: Ian Kent <raven@themaw.net>

Coverity: error[doubleFree]: Memory pointed to by 'root' is freed twice

No it's not, but root isn't freed before the fatal call which crashes
automount so add a free() before the fatal() call.

It appears Coverity doesn't recognise pthread_exit() as an exit condition.
