USB: gadget: f_rndis: fix bitrate for SuperSpeed and above

Browse Source 
commit b00f444f9add39b64d1943fa75538a1ebd54a290 upstream.

Align the SuperSpeed Plus bitrate for f_rndis to match f_ncm's ncm_bitrate
defined by commit 1650113888fe ("usb: gadget: f_ncm: add SuperSpeed descriptors
for CDC NCM").
