RDMA/qedr: Dispatch port active event from qedr_add


[ Upstream commit f449c7a2d822c2d81b5bcb2c50eec80796766726 ]

Relying on qede to trigger qedr on startup is problematic. When probing
both if qedr loads slowly then qede can assume qedr is missing and not
trigger it. This patch adds a triggering from qedr and protects against
a race via an atomic bit.
