drm/msm/dpu: remove unused refcount for encoder_phys_wb

Browse Source 
Remove the unused local variable refcount for encoder_phys_wb
as the one part of wb_enc is used directly.

changes in v2:
	- remove usage of ret variable also
	- remove the if (ret) code as it was dead-code anyway

Fixes: d7d0e73f7d ("drm/msm/dpu: introduce the dpu_encoder_phys_* for writeback")
