    fsck.gfs2: small parameter passing optimization
    
    This patch is a small optimization in a very often-used function,
    done for performance purposes.  Function handle_di in pass1 derives
    the block number from the buffer already passed in rather than
    having the block number passed in as well, and wasting time
    pushing it to the stack and off the stack.
