nfsd: Fix independence of a few nfsd related headers

An header should be compilation independent, .i.e pull in
any header who's declarations are directly used by this header.
And not let users re-include all it's dependencies all over
again.

[At the end of the day what's the use of a header if it does
 not have more then one user?]
