Subject: [PATCH -next] usb: ohci-s3c2410: Remove set but not used variable 'hcd'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/usb/host/ohci-s3c2410.c: In function s3c2410_hcd_oc:
drivers/usb/host/ohci-s3c2410.c:296:18: warning: variable hcd set but not used [-Wunused-but-set-variable]

It is never used, so can be removed.
