gtp-kernel: Fix tunnel creation/removal for GTP Version 1

When Linux Kernel GTP-U support is enabled, OpenGGSN so far only worked
with GTPv0,but not with GTPv1, as the TEI values were not correctly
configured.  This patch fixes the initialzation of the local and remote
TEI before using libgtpnl to create a tunnel context in the kernel.
