Documentation: kernel-parameters: sort NFS parameters

Sort the NFS kernel command line parameters. This is done in 4 groups
so as to not have them intermingled: 'nfs' module parameters, 'nfs4'
module parameters, 'nfsd' module parameters, and nfs "global" (__setup,
no module) parameters.

There were 5 parameters which were listed with a space between the
parameter name and the following '=' sign. The space has been
removed since module parameters expect 'parameter=' with no intervening
space.
