History
Brian Somers 98fff6b57c Account for di_blocks allocations when IN_SPACECOUNTED is set in an 
inode's i_flag.

It's possible that after ufs_infactive() calls softdep_releasefile(),
i_nlink stays >0 for a considerable amount of time (> 60 seconds here).
During this period, any ffs allocation routines that alter di_blocks
must also account for the blocks in the filesystem's fs_pendingblocks
value.

This change fixes an eventual df/du discrepency that will happen as
the result of fs_pendingblocks being reduced to <0.

The only manifestation of this that people may recognise is the
following message on boot:

    /somefs: update error: blocks -N files M

at which point the negative pending block count is adjusted to zero.
