NFSD: hide unused svcxdr_dupstr() 

There is now only one caller left for svcxdr_dupstr() and this is inside
of an #ifdef, so we can get a warning when the option is disabled:

fs/nfsd/nfs4xdr.c:241:1: error: 'svcxdr_dupstr' defined but not used [-Werror=unused-function]

This changes the remaining caller to use a nicer IS_ENABLED() check,
which lets the compiler drop the unused code silently.

Fixes: e40d99e6183e ("NFSD: Clean up symlink argument XDR decoders")
