[PATCH] drm/amd/display: Remove the redundant NULL check

[Ваторопин Андрей]

From: Andrey Vatoropin <a.vatoropin at crpt.ru>

Static analysis shows that pointer "timing" cannot be NULL because it
points to the object "struct dc_crtc_timing".

Remove the extra NULL check. It is meaningless and harms the readability
of the code.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
