Revert "usb: gadget: rndis: Add new rndis parameters"

This reverts commit f645ecc0.

Instead, when gsi_setup() is returning the response payload for
RNDIS_MSG_INIT_C, override the MaxPacketsPerTransfer,
MaxTransferSize and PacketAlignmentFactor fields with the
packet aggregation size that GSI supports for uplink.
