Revert "xfs: fix filesystsem freeze race in xfs_trans_alloc"
This reverts commit 7a249cf83da1813cfa71cfe1e265b40045eceb47.
That commit created a situation that could lead to a filesystem
hang. As Dave Chinner pointed out, xfs_trans_alloc() could hold a
reference to m_active_trans (i.e., keep it non-zero) and then wait
for SB_FREEZE_TRANS to complete. Meanwhile a filesystem freeze
request could set SB_FREEZE_TRANS and then wait for m_active_trans
to drop to zero. Nobody benefits from this sequence of events...
