[PATCH 02/27] ext4: don't explicit update times in ext4_fallocate()

[Zhang Yi <yi.zhang@huaweicloud.com>]

From: Zhang Yi <yi.zhang@huawei.com>

After commit 'ad5cd4f4ee4d ("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.
