[PATCH] ip_conntrack: fix ftp/irc/tftp helpers on ports >= 32768

Browse source 
Since we've converted the ftp/irc/tftp helpers to use the new
module_parm_array() some time ago, we ware accidentially using signed data
types - thus preventing those modules from being used on ports >= 32768.

This patch fixes it by using 'ushort' module parameters.

Thanks to Jan Nijs for reporting this bug.
