net: hso: fix control-request directions

commit 1a6e9a9c68c1f183872e4bcc947382111c2e04eb upstream.

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().
