If the call to adjust_shared_perm() fails, lock_file returns -1, which
to the caller looks like any other failure to lock the file. So in
this case, roll back the lockfile before returning so that the lock
file is deleted immediately and the lockfile object is left in a
predictable state (namely, unlocked). Previously, the lockfile was
retained until process cleanup in this situation.
