Stanislaw Gruszka bf4c02d5e7 rt2x00: reset usb devices at probe 
When module is reloaded, device may fail to work, with messages:

[  342.211926] phy40 -> rt2x00lib_rxdone_read_signal: Warning - Frame received with unrecognized signal, mode=0x0000, signal=0x0059, type=2.

Whereas replugging device make it functional. To solve that problem
force reset device during probe.

With patch messages are gone. Unfortunately device may sometimes
still does not operate correctly after module reload (fail to receive
data after associate), but such cases are rarer than without the patch.
