Subject: [PATCH] USB: c67x00: remove redundant pointer urbp

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

Pointer urbp is assigned but is never read, hence it is redundant
and can be removed. Cleans up clang warning:

drivers/usb/c67x00/c67x00-sched.c:975:2: warning: Value stored to 'urbp'
is never read
