drm/amdgpu: fixing rlc firmware loading failure issue

Skip rlc firmware validation to ignore firmware header size mismatch issues.
This restores the workaround added in
commit 849e133 ("drm/amdgpu: Fix the null pointer when load rlc firmware")

Fixes: 3af2c80 ("drm/amdgpu: refine gfx10 firmware loading")
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3551
