Trond Myklebust 41d4cc6b58 NFS: finish_automount() requires us to hold 2 refs to the mount record 
[ Upstream commit 75da98586a ]

We must not return from nfs_d_automount() without holding 2 references
to the mount record. Doing so, will trigger the BUG() in finish_automount().
Also ensure that we don't try to reschedule the automount timer with
a negative or zero timeout value.

Fixes: 22a1ae9a93 ("NFS: If nfs_mountpoint_expiry_timeout < 0, do not expire submounts")
