drm/msm/dp: use dp_ctrl_off_link_stream during PHY compliance test run

Browse Source 
DP cable should always connect to DPU during the entire PHY compliance
testing run. Since DP PHY compliance test is executed at irq_hpd event
context, dp_ctrl_off_link_stream() should be used instead of dp_ctrl_off().
dp_ctrl_off() is used for unplug event which is triggered when DP cable is
dis connected.

Changes in V2:
-- add fixes statement

Fixes: f21c8a276c ("drm/msm/dp: handle irq_hpd with sink_count = 0 correctly")
