Subject: [PATCH] IPVS: ip_vs_ftp.c: local functions should not be exposed globally

Functions not referenced outside of a source file should be marked
static to prevent it from being exposed globally.

This quiets the sparse warnings:

warning: symbol 'ip_vs_ftp_init' was not declared. Should it be static?
