Jerry Zuo e8cd26434d drm/amd/display: Use atomic types for ref_count 
Current ref_count inc/dec is not guarded by locks which leads to
a raced condition where two threads try to access the variable
at the same time. In this case, both might act on the same cached
value and inc/dec from the same value, rather than inc/dec by 2.
