Fix a lock contention issue by allowing threads not holding ZPL locks to block when waiting to assign a transaction. Porting Notes: zfs_putpage() still uses TXG_NOWAIT, unlike the upstream version. This case may be a contention point just like zfs_write(), however it is not safe to block here since it may be called during memory reclaim.
