Subject: drm/amd/display: Fix memleak in amdgpu_dm_mode_config_init
Git-commit: b67a468a4ccef593cd8df6a02ba3d167b77f0c81
Patch-mainline: v5.9-rc3
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

When amdgpu_display_modeset_create_props() fails, state and
state->context should be freed to prevent memleak. It's the
same when amdgpu_dm_audio_init() fails.
