[ Upstream commit 047ae66557 ]
kzalloc() is a memory allocation function which can return NULL when
some internal memory errors happen. So it is better to check it to
prevent potential wrong memory access.
Besides, since mdp5_plane_reset() is void type, so we should better
set `plane-state` to NULL after releasing it.
