USB: adutux: remove redundant variable minor

commit 8444efc4a052332d643ed5c8aebcca148c7de032 upstream.

Variable minor is being assigned but never read, hence it is redundant
and can be removed. Cleans up clang warning:

drivers/usb/misc/adutux.c:770:2: warning: Value stored to 'minor' is
never read

[bwh: Backported to 3.16 so that commit 44efc269db79 "USB: adutux: fix
 use-after-free on disconnect" applies cleanly]
