    nfsd: Clean up the "glue" for the nfsrdma.ko module
    
    Move svc_reg() calls into a helper function so that the nfsrdma.ko
    can call that.  Create a new nfs_extern.h as a place to put the
    nfs stuff that server side NFS over RDMA needs to access, with a
    prototype for the helper function and a couple of definitions that
    probably shouldn't be in svc.h.
    
    No semantics change.
    
    MFC after:      3 months
    Fixes:  7144a1d58c5c ("nfsd: Add glue for the nfsrdma.ko module")
