drm/amdkfd: fix double free device pgmap resource

Browse source

Use devm_memunmap_pages instead of memunmap_pages to release pgmap
and remove pgmap from device action, to avoid double free pgmap when
unloading driver module.

Release device memory region if failed to create device memory pages
structure.
