autofs4: use autofs_info for pending flag

Browse source

Eliminate the use of the d_lock spin lock by using the autofs super block
info spin lock.  This reduces the number of spin locks we use by one and
makes the code for the following patch (to redirect ->d_revalidate() to
->lookup()) a little simpler.
