HID: logitech-hidpp: Stop IO before calling hid_connect()

HID: logitech-hidpp: Stop IO before calling hid_connect()

hid_connect() will call hid_pidff_init() which does
hid_device_io_start() leading to an "io already started" warning.

To fix this call hid_device_io_stop() before calling hid_connect(),
stopping IO means that connect events may be lost while hid_connect()
runs, re-enable IO and move the hidpp_connect_event() work queuing
after the hid_connect().

Note re-enabling IO is also necessary for the g920_get_config()
call later during hidpp_probe().
