Before this patch, gfs2 would deadlock because of the following
sequence during mount:
mount
gfs2_fill_super
gfs2_make_fs_rw <--- Detects IO error with glock
kthread_stop(sdp->sd_quotad_process);
<--- Blocked waiting for quotad to finish
logd
Detects IO error and
Before this patch, in the unlikely event that gfs2_glock_dq encountered a
withdraw, it would do a wait_on_bit to wait for its journal to be
recovered, but it never released the glock's spin_lock, which caused a
scheduling-while-atomic error.
This patch unlocks the lockref spin_lock before waiting
