mt76: mt7915: fix bit fields for HT rate idx
[ Upstream commit 47f1c08db7f3aaa2d13f8e56209375462ace7b8a ]
The bit fields of tx rate idx should be 6 bits, otherwise it might be
incorrect in HT mode.
For VHT/HE rates, only 4 bits are actually used by rate idx, the other
2 bits are used for other functions.
