[ Upstream commit 3954502377 ]
Disallow bind() calls that have the same arguments as existing bound
sockets. Previously multiple sockets could bind() to the same
type/local address, with an arbitrary socket receiving matched messages.
This is only a partial fix, a future commit will define precedence order
for MCTP_ADDR_ANY versus specific EID bind(), which are allowed to exist
together.
