staging: lustre: libcfs/nidstrings: Declare internal symbols static 

This fixes sparse warnings:
  staging/lustre/lustre/libcfs/nidstrings.c:200:11: warning: symbol 'libcfs_nnetstrfns' was not declared. Should it be static?
  drivers/staging/lustre/lustre/libcfs/nidstrings.c:203:1: warning: symbol 'libcfs_lo_str2addr' was not declared. Should it be static?
  drivers/staging/lustre/lustre/libcfs/nidstrings.c:210:1: warning: symbol 'libcfs_ip_addr2str' was not declared. Should it be static?

  drivers/staging/lustre/lustre/libcfs/nidstrings.c:307:18: warning: symbol 'libcfs_name2netstrfns' was not declared. Should it be static?

Some functions had static forward declarations followed by non-static
implementations. Those forward declarations are removed and the
implementations are declared static and moved into a location that
doesn't require forward declarations.
