autofs-5.1.4 - fix deadlock in dumpmaps
From: Ian Kent <raven@themaw.net>
Commit a223d11fa8e (autofs-5.1.3 - serialize calls to open_xxxx()
functions) introduces a deadlock when using the dumpmaps function.
In this case the open fd mutex needs to be unlocked in the forked
child process of the do_spawn() function.
