Jun Yan 8309c947b2 USB: usblp: return error when setting unsupported protocol 
commit 7a3d76a0b6 upstream.

Fix the regression introduced by commit d8c6edfa3f ("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.

Fixes: d8c6edfa3f ("USB: usblp: don't call usb_set_interface if there's a single alt")
