disp: msm: dp: Release connector reference after reading crc frame value

Browse Source 
This change decrements the specific drm connector's reference count
after it has been used for reading crc frame value. Without this
change, there might be a chance of a connector's reference count
still remaining positive, even if it is not accessed anywhere
further in code.
