media: mediatek: vcodec: Fix a resource leak related to the scp device in FW initialization

Browse Source 
On Mediatek devices with a system companion processor (SCP) the mtk_scp
structure has to be removed explicitly to avoid a resource leak.
Free the structure in case the allocation of the firmware structure fails
during the firmware initialization.

Fixes: 53dbe08504 ("media: mtk-vcodec: potential null pointer deference in SCP")
