[PATCH AUTOSEL 5.9 052/111] rtw88: increse the size of rx buffer size

[Sasha Levin]

From: Tzu-En Huang <tehuang@xxxxxxxxxxx>

[ Upstream commit ee755732b7a16af018daa77d9562d2493fb7092f ]

The vht capability of MAX_MPDU_LENGTH is 11454 in rtw88; however, the rx
buffer size for each packet is 8192. When receiving packets that are
larger than rx buffer size, it will leads to rx buffer ring overflow.
