    kern_jail.c: Remove #ifdefs for VNET_NFSD
    
    The consensus was that VNET_NFSD was not needed.
    This patch removes it from kern_jail.c.
    
    With this patch, support for the "allow.nfsd"
    jail parameter is enabled in the kernel for
    kernels built with "options VIMAGE".
    
    (cherry picked from commit cbbb22031f9b957967c03dc8e685392f7d7e7fb8)
