Subject: [PATCH 1/2] Revert "media: rtl28xxu: fix zero-length control request"

This reverts commit 25d5ce3a606a1eb23a9265d615a92a876ff9cb5f.

The patch in question causes a regression and was superseded by a second
version. Unfortunately, the first revision ended up being applied
instead of the correct one.
