imx415_set_testpattern() accumulates failures from cci_write(), but drops
the value and always returns success. Return the accumulated error so V4L2
reports failures to userspace.

The VBLANK path returned immediately when programming VMAX failed after
pm_runtime_get_if_in_use() had taken a runtime PM reference. Break out of
the switch instead so the common pm_runtime_put() path is used.
