Subject: [PATCH] usb: isp1760: remove redundant variable 'selector'

From: Colin Ian King <colin.king@...onical.com>

Variable 'selector'  is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'selector' set but not used [-Wunused-but-set-variable]
