rds: don't let RDS shutdown a connection while senders are present
This is the first in a long line of patches that tries to fix races between RDS connection shutdown and RDS traffic. Here we are maintaining a count of active senders to make sure the connection doesn't go away while they are using it. Signed-off-by: Chris Mason <chris.mason@oracle.com>
