Clock should be turned off after calling s5p_mfc_init_hw() from the
watchdog worker, like it is already done in the s5p_mfc_open() which also
calls this function.

Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com>
Fixes: af93574678108 ("[media] MFC: Add MFC 5.1 V4L2 driver")
CC: stable@vger.kernel.org # v3.7+
---
This issue was there from the beggining of the driver, but this patch applies
cleanly only to v3.7+ kernels.
