This commit addresses a memleak issue of panthor_vma (or drm_gpuva)
structure in Panthor driver, that can happen if the GPU page table
update operation to map the pages fail.
The issue is very unlikely to occur in practice.
v2: Add panthor_vm_op_ctx_return_vma() helper (Boris)
v3: Add WARN_ON_ONCE (Boris)
Fixes: 647810ec24 ("drm/panthor: Add the MMU/VM logical block")
