Subject: [PATCH 5/7] USB: gadget: f_mass_storage: remove needless complete()

From: Michal Nazarewicz <mina86@...a86.com>

This commit removes call to the complete() function done in
fsg_unbind() which was never needed there but was a leftover
form file_storage.c.

An additional complete() didn't hurt but at the same time it was
rather useless.
