[PATCH 32/36] drm/amd/display: Remove redundant checks for context

[Hamza Mahfooz]

From: Alex Hung <alex.hung at amd.com>

The null checks for context are redundant as it was already
dereferenced previously, as reported by Coverity; therefore
the null checks are removed.

This fixes 2 REVERSE_INULL issues reported by Coverity.
