drm/amdgpu: ensure all userq VAs mapped before restore

Browse source

amdgpu_userq_buffer_vas_mapped() checks whether all VAs
of a queue are mapped before restoring it.
So that HW won't access any invalid addresses.

Currently, this function assumes all VAs are mapped if
any VA of a queue has been mapped, which is wrong.

This commit fixes this problem by examining all VAs of
a queue and reporting false if any of them is not mapped.
