Junxiao Bi da6e651294 ocfs2: fix panic due to unrecovered local alloc 
[ Upstream commit 532e1e54c8 ]

mount.ocfs2 ignore the inconsistent error that journal is clean but
local alloc is unrecovered.  After mount, local alloc not empty, then
reserver cluster didn't alloc a new local alloc window, reserveration
map is empty(ocfs2_reservation_map.m_bitmap_len = 0), that triggered the
following panic.

This issue was reported at

  https://oss.oracle.com/pipermail/ocfs2-devel/2015-May/010854.html

and was advised to fixed during mount.  But this is a very unusual
inconsistent state, usually journal dirty flag should be cleared at the
last stage of umount until every other things go right.  We may need do
further debug to check that.  Any way to avoid possible futher
corruption, mount should be abort and fsck should be run.
