ext4: remove redundant offset check in mext_check_arguments()
In the check code above, if orig_start != donor_start, we would return -EINVAL. So here, orig_start should be equal with donor_start. Remove the redundant check here. Signed-off-by: Wang Sheng-Hui <shhuiw@gmail.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
