SYNC_BDFLUSH is a leftover from IRIX and rather misnamed for todays code. Make xfs_sync_fsdata and xfs_dq_sync use the SYNC_TRYLOCK flag for not blocking on logs just as the inode sync code already does. For xfs_sync_fsdata it's a trivial 1:1 replacement, but for xfs_qm_sync I use the opportunity to decouple the non-blocking lock case from the different flushing modes, similar to the inode sync code.
