[PATCH AUTOSEL 5.7 158/274] media: sun8i: Fix an error handling path in 'deinterlace_runtime_resume()'

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit 62eedb356188376acd0368384a9b294d5180c00b ]

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.
