f2fs: fix not to allocate unnecessary blocks during fallocate
This patch fixes the fallocate bug like below. (See xfstests/255)
In fallocate(fd, 0, 20480),
expand_inode_data processes
for (index = pg_start; index <= pg_end; index++) {
f2fs_reserve_block();
...
}
So, even though fallocate requests 20480, 5 blocks, f2fs allocates 6 blocks
including pg_end.
So, this patch adds one condition to avoid block allocation.
