USB: usblp: return error when setting unsupported protocol
Fix the regression introduced by commit d8c6edfa3f4e ("USB:
usblp: don't call usb_set_interface if there's a single alt"),
which causes that unsupported protocols can also be set via
ioctl when the num_altsetting of the device is 1.
Move the check for protocol support to the earlier stage.
