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.
