Instead of returning a generic NULL on error from
drm_dp_tunnel_mgr_create(), use error pointers with informative codes
to align the function with stub that is executed when
CONFIG_DRM_DISPLAY_DP_TUNNEL is unset. This will also trigger IS_ERR()
in current caller (intel_dp_tunnerl_mgr_init()) instead of bypassing it
via NULL pointer.
v2: use error codes inside drm_dp_tunnel_mgr_create() instead of handling
on caller's side (Michal, Imre)
v3: fixup commit message and add "CC"/"Fixes" lines (Andi),
mention aligning function code with stub
