drm/amdgpu: fix hung reset queue array memory allocation
By design the MES will return an array result that is twice the number
of hung doorbells it can report.
i.e. if up k reported doorbells are supported, then the
second half of the array, also of length k, holds the HQD information
(type/queue/pipe) where queue 1 corresponds to index 0 and k,
queue 2 corresponds to index 1 and k + 1 etc ...
The driver will use the HDQ info to target queue/pipe reset for
hardware scheduled user compute queues.
