ocfs2: mark dquot as inactive if failed to start trans while releasing dquot

Browse Source 
[ Upstream commit 276c61385f6bc3223a5ecd307cf4aba2dfbb9a31 ]

While running fstests generic/329, the kernel workqueue
quota_release_workfn is dead looping in calling ocfs2_release_dquot().
The ocfs2 state is already readonly but ocfs2_release_dquot wants to
start a transaction but fails and returns.

ocfs2_release_dquot() is much like dquot_release(), which is called by
ext4 to handle similar situation.  So here fix it by marking the dquot as
inactive like what dquot_release() does.
