net: hso: fix control-request directions
The direction of the pipe argument must match the request-type direction
bit or control requests may fail depending on the host-controller-driver
implementation.
Fix the tiocmset and rfkill requests which erroneously used
usb_rcvctrlpipe().
Fixes: 72dc1c096c70 ("HSO: add option hso driver")
