[PATCH] ext4: remove unneeded call to ext4_es_remove_extent in punch hole

[Ashish Sangwan <ashishsangwan2@gmail.com>]

From: Ashish Sangwan <a.sangwan@samsung.com>

During punch hole, before removing extents we make sure that the blocks
are commited to disk by calling filemap_write_and_wait_range. So, the
extents cannot be present on extent status tree.
