    nfsd: Return ENXIO instead of EPERM when nfsd(8) already running
    
    The nfsd(8) daemon generates an error message that does not
    indicate that the nfsd daemon is already running when the nfssvc(2)
    syscall fails for the NFSSVC_STABLERESTART.  Also, the check for
    running nfsd(8) in a vnet prison will return EPERM when it fails.
    
    This patch replaces EPERM with ENXIO so that the nfsd(8) daemon
    can generate more reasonable failure messages.  The nfsd(8) daemon
    will be patched in a future commit.
