gtp: do not allow adding duplicate tid and ms_addr pdp context
[ Upstream commit 6b01b1d9b2d38dc84ac398bfe9f00baff06a31e5 ]
GTP RX packet path lookups pdp context with TID. If duplicate TID pdp
contexts are existing in the list, it couldn't select correct pdp context.
So, TID value should be unique.
GTP TX packet path lookups pdp context with ms_addr. If duplicate ms_addr pdp
contexts are existing in the list, it couldn't select correct pdp context.
So, ms_addr value should be unique.
