nfsd: Add glue for the nfsrdma.ko module

Thanks to Vinicius Ferrao <versatushpc.com.br>, there
is now a module that implements the server side of RDMA
for the FreeBSD NFS server.

At least for now, it will be maintained as an "unofficial
port" for FreeBSD, since it was built with generative AI
and FreeBSD is working on a policy related to these submissions.

This patch puts the "glue" needed by Vinicius's nfsrdma.ko
module in the system.  This "glue" was written by me without
the use of AI.

The "unofficial port" of nfsrdma.ko will be advertised on
freebsd-current@ as soon as it is available.
(Vinicius's work was sponsored by VersatupHPC.)

Since newnfs_numnfsd is now declared extern in nfs.h,
the extern declaration can be removed from assorted files.
I'll do that as a separate commit.
