[PATCH] drm/amdgpu: fix failure mapping legacy queue when FLR

[Lin.Cao]

Flag "mes.ring.shced.ready" will be set as true after mes hw init and set
as false when mes hw fini to avoid duplicate initialization. But hw fini
will not be called when function level reset, which will cause mes hw
init be skipped during FLR, which will leads to mapping legacy queue
fail. Set this flag as false when post reset will fix this issue.
