gtp: set NLM_F_MULTI flag in gtp_genl_dump_pdp()

Browse Source 
[ Upstream commit 846c68f7f1ac82c797a2f1db3344a2966c0fe2e1 ]

In drivers/net/gtp.c, gtp_genl_dump_pdp() should set NLM_F_MULTI
flag since it returns multipart message.
This patch adds a new arg "flags" in gtp_genl_fill_info() so that
flags can be set by the callers.
