kernel - Do a better job with the filesystem background sync
* Adjust code for MNT_LAZY, MNT_NOWAIT, and MNT_WAITOK to reflect
the fact that they are three different flags and not enumeration
constants.
* HAMMER now sets VMSC_ONEPASS for MNT_LAZY syncs (background filesystem
sync). This generally reduces instances where the background sync
winds up running continuously when heavy filesystem ops saturate
the disk. Fewer vnodes dirtied after the sync is initiated will get
caught up in the sync.
