qcacld-3.0: Enable UL MU for 5g/6g

UL MU is not enabled in 5G HE capability.

HE global configuration is populated by averaging
all the hardware modes capabilities. UL MU is disabled
in 2G mode so global capability UL MU is disabled.
Modified code to obtain the UL MU capability from 5G specific
capability structure.
