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.
Fixes: 949f1e39a617 ("bridge: mdb: notify on router port add and del")
