USB: gadget: udc: fix const issue in gadget_match_driver()

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

gadget_match_driver() 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.
