[PATCH 09/67] drm/amd/display: Remove unreachable check

[Zaeem Mohamed]

From: Ivan Lipski <ivlipski at amd.com>

[WHY]
Coverity analysis flagged this code as DEADCODE
since the condition and return in the outer loop
are never reached.

All operations with the 'dwb_pipe' variable happen
in the inner loop, that already contains the same
check with the 'MAX_DWB_PIPES'. The later
check condition cannot occur before the check
condition in the inner loop, thus the later
condition is unreacable.

[HOW]
Remove the unreachable condition.
