gfs2: Fix an incorrect gfs2_assert()
When updating the inode information after a change in allocation,
convert the change into the same units as the inode's i_blocks count
before comparing it in an assertion.
Also, change the comparison so that it is still possible to set i_blocks
to zero by adding -i_blocks, something that was previously only possible
because of the difference in units.
