media: mtk-mdp: Fix error handling in probe function

Browse source

[ Upstream commit 8a8a3232ab ]

Add mtk_mdp_unregister_m2m_device() on the error handling path to prevent
resource leak.

Add check for the return value of vpu_get_plat_device() to prevent null
pointer dereference. And vpu_get_plat_device() increases the reference
count of the returned platform device. Add platform_device_put() to
prevent reference leak.
