[media] s5p-fimc: Don't ignore return value of vb2_queue_init()

Add missing checks for return value of vb2_queue_init(), after
this function has been modified recently to not throw BUG_ON().
This eliminates related compiler warnings,
drivers/media/platform/s5p-fimc/fimc-lite.c: In function fimc_lite_subdev_registered:
drivers/media/platform/s5p-fimc/fimc-lite.c:1256:16: warning: ignoring return value
of vb2_queue_init, declared with attribute warn_unused_result [-Wunused-result]
drivers/media/platform/s5p-fimc/fimc-capture.c: In function fimc_register_capture_device:
drivers/media/platform/s5p-fimc/fimc-capture.c:1739:16: warning: ignoring return value
of vb2_queue_init, declared with attribute warn_unused_result [-Wunused-result]
