[PATCH 1/1] USB: gadget: function: Deletion of an unnecessary check before the function call "rndis_add_hdr"

The rndis_add_hdr() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
