Revert "mt76: use IEEE80211_OFFLOAD_ENCAP_ENABLED instead of MT_DRV_AMSDU_OFFLOAD"

Browse Source 
This reverts commit f17f4864504d754bcbf31e4c89412cdf9946c409.

The reverted commit significantly decreases performance when running
a test where two MT7915 radios have 16 station vdevs each, configured
for AC mode, and transmitting UDP traffic to AP.
