Stanislaw Gruszka 8f2d163cb2 mt76: mt76x0u: do not reset radio on resume
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!

[  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.
