Nicolas Dichtel 7a55aba16c bridge/mdb: remove wrong use of NLM_F_MULTI
[ Upstream commit 94a72b3f024fc7e9ab640897a1e38583a470659d ]

NLM_F_MULTI must be used only when a NLMSG_DONE message is sent at the end.
In fact, NLMSG_DONE is sent only at the end of a dump.

Libraries like libnl will wait forever for NLMSG_DONE.
