vmalloc: update __vmalloc_node_noprof() documentation
The kernel-doc for __vmalloc_node_noprof() incorrectly states that
__GFP_NOFAIL reclaim modifier is not supported. In fact it has been
supported since commit 9376130c390a ("mm/vmalloc: add support for
__GFP_NOFAIL").
To avoid duplication and future drift, point this helper's doc to
__vmalloc_node_range_noprof() for details and the full description.
