drm/connector: hdmi: Handle reset() state allocation failure
In drmm_connector_hdmi_init(), if the reset callback fails to allocate
memory, e.g. inside drm_atomic_helper_connector_reset(),
connector->state will remain NULL. This is unconditionally passed to
drm_connector_attach_max_bpc_property(), leading to a NULL pointer
dereference.
Bail out with -ENOMEM if the reset callback leaves connector->state
unset.
