wifi: rtw89: pci: enlarge RX DMA buffer to consider size of RX descriptor

Browse source

[ Upstream commit c108b4a50d ]

Hardware puts RX descriptor and packet in RX DMA buffer, so it could be
over one buffer size if packet size is 11454, and then it will be split
into two segments. WiFi 7 chips use larger size of RX descriptor, so
enlarge DMA buffer size according to RX descriptor to have better
performance and simple flow.
