    jfs: fix regression preventing coalescing of extents
    
    Commit fec1878fe952b994125a3be7c94b1322db586f3b caused a regression in
    which contiguous blocks being allocated to the end of an extent were
    getting a new extent created.  This typically results in files entirely
    made up of 1-block extents even though the blocks are contiguous on
    disk.
    
    Apparently grub doesn't handle a jfs file being fragmented into too many
    extents, since it refuses to boot a kernel from jfs that was created by
    the 2.6.30 kernel.
