Huai-Yuan Liu e4b52d4938 drm/arm/malidp: fix a possible null pointer dereference ...

[ Upstream commit a1f95aede6 ]

In malidp_mw_connector_reset, new memory is allocated with kzalloc, but
no check is performed. In order to prevent null pointer dereferencing,
ensure that mw_state is checked before calling
__drm_atomic_helper_connector_reset.
