mt76: mt76x0u: do not reset radio on resume
commit 8f2d163cb26da87e7d8e1677368b8ba1ba4d30b3 upstream.
On some machines mt76x0u firmware can hung during resume,
what result on messages like below:
[ 475.480062] mt76x0 1-8:1.0: Error: MCU response pre-completed!
[ 475.990066] mt76x0 1-8:1.0: Error: send MCU cmd failed:-110

[ 477.825029] usb 1-8: USB disconnect, device number 6
and possible whole system freeze.
This can be avoided, if we do not perform mt76x0_chip_onoff() reset.
