autofs4 - fix reset pending flag on mount fail

commit 49999ab27eab6289a8e4f450e148bdab521361b2 upstream.

In autofs4_d_automount(), if a mount fail occurs the AUTOFS_INF_PENDING
mount pending flag is not cleared.

One effect of this is when using the "browse" option, directory entry
attributes show up with all "?"s due to the incorrect callback and
subsequent failure return (when in fact no callback should be made).
