mt76: mt76u: reduce rx memory footprint

Browse source 
Reduce rx memory footprint allocating just one SG buffer since for the
moment we support just 3839B as maximal size of an A-MSDU.
Introduce different SG_MAX_SIZE definitions for TX and RX sides.
Moreover set q->buf_size to PAGE_SIZE even for SG case.
