reorganize ffs_truncate()/ffs_indirtrunc() to be able to partially
...
succeed; change wapbl_register_deallocation() to return EAGAIN
rather than panic when code hits the limit
callers changed to either loop calling ffs_truncate() using new
utility ufs_truncate_retry() if their semantics requires it, or
just ignore the failure; remove ufs_wapbl_truncate()
this fixes possible user-triggerable panic during truncate, and
resolves WAPBL performance issue with truncates of large files

adjust ffs_realloccg() so that the logic about allocating full
...
contiguous block for future fragment expansion doesn't need to
UFS_WAPBL_REGISTER_DEALLOCATION() or ffs_blkfree(); the free blocks
are now immediatelly available for use by the expanding file in further i/o
primary driver is safe removal of the deallocation registration and
hence failure point, but this also fixes degenerate case for wapbl,
and similar also for discard - if the file would be actually expanded
before wapbl commit, or before discard queue would be processed,
the filesystem would not yet see the contiguous free blocks, and
would be forced to allocate another fragment elsewhere
