When wifi is under scanning/linking/roaming, do not run the reset of the

table parameters to make wfi and bt coexist smoothly. Otherwise the
bt may have low sound quality or mouse lag, which mean bad user
experience. The same problem may occur on wifi also, if could disconnect
or lose some important packets.
