Jan Kara 80d73f15d1 ocfs2: Fix possible deadlock in quota recovery 
In ocfs2_finish_quota_recovery() we acquired global quota file lock and started
recovering local quota file. During this process we need to get quota
structures, which calls ocfs2_dquot_acquire() which gets global quota file lock
again. This second lock can block in case some other node has requested the
quota file lock in the mean time. Fix the problem by moving quota file locking
down into the function where it is really needed.  Then dqget() or dqput()
won't be called with the lock held.
