When a block group is composed of a sequential write zone and a
conventional zone, we recover the (pseudo) write pointer of the
conventional zone using the end of the last allocated position.
However, if the last extent in a block group is removed, the last extent
position will be smaller than the other real write pointer position.
Then, that will cause an error due to mismatch of the write pointers.
We can fixup this case by moving the alloc_offset to the corresponding
write pointer position.
