bluetooth: hidp_process_hid_control remove unnecessary parameter dealing
According to the bluetooth HID spec v1.0 chapter 7.4.2
"This code requests a major state change in a BT-HID device. A HID_CONTROL
request does not generate a HANDSHAKE response."
"A HID_CONTROL packet with a parameter of VIRTUAL_CABLE_UNPLUG is the only
HID_CONTROL packet a device can send to a host. A host will ignore all other
packets."
So in the hidp_precess_hid_control function, we just need to deal with the
UNLUG packet.
