Andreas Gruenbacher 3429ef5f50 gfs2: Fix NULL pointer dereference in gfs2_log_flush 
[ Upstream commit 35264909e9d1973ab9aaa2a1b07cda70f12bb828 ]

In gfs2_jindex_free(), set sdp->sd_jdesc to NULL under the log flush
lock to provide exclusion against gfs2_log_flush().

In gfs2_log_flush(), check if sdp->sd_jdesc is non-NULL before
dereferencing it.  Otherwise, we could run into a NULL pointer
dereference when outstanding glock work races with an unmount
(glock_work_func -> run_queue -> do_xmote -> inode_go_sync ->
gfs2_log_flush).
