Subject: [PATCH] media: sun8i: Fix an error handling path in 'deinterlace_runtime_resume()'

It is spurious to call 'clk_disable_unprepare()' when
'clk_prepare_enable()' has not been called yet.
Re-order the error handling path to avoid it.

Fixes: a4260ea49547 ("media: sun4i: Add H3 deinterlace driver")
