ext4: don't explicit update times in ext4_fallocate()

[ Upstream commit 73ae756e ]

After commit 'ad5cd4f4 ("ext4: fix fallocate to use file_modified to
update permissions consistently"), we can update mtime and ctime
appropriately through file_modified() when doing zero range, collapse
rage, insert range and punch hole, hence there is no need to explicit
update times in those paths, just drop them.
