ext4: Update i_disksize properly when allocating from fallocate area.
When allocating unitialized space at the end of file which had been
preallocated with the FALLOC_FL_KEEP_SIZE option, the file size is not
updated at that time. But the later we are not updating the file size
when writing to that preallocated space.
These changes are for code correctness. This patch allows us to update
the i_disksize at the write_end() callback of filesystem properly.
