[PATCH] media: ov7740: return error code at ov7740_get_register

[Mauro Carvalho Chehab]

If v4l2_subdev_core_ops.g_register fails, it should be
returning an error code to userspace, instead of zero.

Fixes:
         drivers/media/i2c/ov7740.c: warning: variable 'ret' set but not used 
[-Wunused-but-set-variable]:  => 276:6
