USB: serial: bus: fix const issue in usb_serial_device_match()

[ Upstream commit 92cd405b648605db4da866f3b9818b271ae84ef0 ] usb_serial_device_match() takes a const pointer, and then decides to cast it away into a non-const one, which is not a good thing to do overall. Fix this up by properly setting the pointers to be const to preserve that attribute.

This patch does not need to be backported and I left out the stable patch on purpose as usual.

Please drop.
