sys/vfs/hammer: Change ondisk vol_nblocks/blocksize to reserved
These were added in fbc6e32a in 2007 in the early stage of HAMMER,
but vol_nblocks wasn't used after 9480ff55 in 2008. vol_blocksize
was never used.
HAMMER volumes have these set by newfs_hammer and hammer volume-add,
but today they are just there for nothing (with obvious values).
The existing HAMMER volumes will keep having vol_nblocks/blocksize
fields initially set by newfs_hammer or added by hammer volume-add,
but new volumes created or added from now on will have 0 for these.
It doesn't erase what's in the existing volume headers.
(There shouldn't be external userspace code that refers to these)
