drm/imagination: Fix error path in pvr_vm_create_context
It is possible to double free the vm_ctx->mmu_ctx object in this
function.
630 err_page_table_destroy:
--> 631 pvr_mmu_context_destroy(vm_ctx->mmu_ctx);
The pvr_vm_context_put() function does:
kref_put(&vm_ctx->ref_count, pvr_vm_context_release);
Here the pvr_vm_context_release() will call:
pvr_mmu_context_destroy(vm_ctx->mmu_ctx);
Refactor to an unwind style.
