net: hns3: keep MAC pause mode when multiple TCs are enabled

Browse Source 
[ Upstream commit d78e5b6a6764cb6e83668806b63d74566db36399 ]

Bellow HNAE3_DEVICE_VERSION_V3, MAC pause mode just support one
TC, when enabled multiple TCs, force enable PFC mode.

HNAE3_DEVICE_VERSION_V3 can support MAC pause mode on multiple
TCs, so when enable multiple TCs, just keep MAC pause mode,
and enable PFC mode just according to the user settings.
