[PATCH v4 11/13] ext4: remove ctime/mtime update from ext4_alloc_file_blocks()

[Zhang Yi]

From: Zhang Yi <yi.zhang@xxxxxxxxxx>

The ctime and mtime update is already handled by file_modified() in
ext4_fallocate(), the caller of ext4_alloc_file_blocks(). So remove the
redundant calls to inode_set_ctime_current() and inode_set_mtime_to_ts()
in ext4_alloc_file_blocks().
