bridge/mdb: remove wrong use of NLM_F_MULTI

BugLink: https://bugs.launchpad.net/bugs/1845405

[ Upstream commit 94a72b3f ]

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: 949f1e39 ("bridge: mdb: notify on router port add and del")
