    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...
