[PATCH] drm/msm/dpu: populate wb or intf before reset_intf_cfg

[Abhinav Kumar]

dpu_encoder_helper_phys_cleanup() was not populating neither
wb or intf to the intf_cfg before calling the reset_intf_cfg().

This causes the reset of the active bits of wb/intf to be
skipped which is incorrect.

Fix this by populating the relevant wb or intf indices correctly.
