drm/amd/display: Remove unnecessary variable
[WHY] Coverity analysis flagged this code as DEADCODE because the condition '(!need_recovery)' is never true. The variable 'need_recovery' is initialized as 'true', is not assigned to 'false' anywhere before the conditional statement. Since the variable is only used for the conditional check, but the check can never be true, the variable itself is redundant. [HOW] Removed the variable 'need_recovery'.
