[PATCH 1/2] mm/vmalloc: use free_vm_area() if an allocation fails

["Uladzislau Rezki (Sony)" <urezki@gmail.com>]

There is a dedicated and separate function that finds and
removes a continuous kernel virtual area. As a final step
it also releases the "area", a descriptor of corresponding
vm_struct.

Use free_vmap_area() in the __vmalloc_node_range() instead
of open coded steps which are exactly the same, to perform
a cleanup.
