vmalloc: export vrealloc_node_align_noprof
This symbol is used from the Nova driver, so it needs to be exported to
avoid a build failure when building Nova as a module.
ERROR: modpost: "vrealloc_node_align_noprof" [drivers/gpu/nova-core/nova_core.ko] undefined!
ERROR: modpost: "vrealloc_node_align_noprof" [samples/rust/rust_dma.ko] undefined!
This error is only triggered if helpers are inlined into Rust. Otherwise,
Nova will call the exported symbol
rust_helper_vrealloc_node_align()
instead. There is no Fixes: tag as that feature is still WIP.
I used non-GPL EXPORT_SYMBOL to match the rest of the file, but let me
know if I should use EXPORT_SYMBOL_GPL.
