drm/amdgpu/mes: Fix hung_queue_db_array loop limit for multi-XCC
The loop iterated only AMDGPU_MAX_MES_PIPES times, leaving entries
uninitialized for multi-XCC GPUs. This causes null pointer dereferences
when accessing arrays indexed by XCC ID >= 2. Extend the loop to cover
all XCCs (AMDGPU_MAX_MES_PIPES * num_xcc), matching other per-XCC
arrays.
Fixes: a132fc9bc2f8 ("drm/amdgpu: Fixup boost mes detect hang array size")
