Bug? receiver bind being created when transceiver-mode is enabled and receive-port is also specified

Hi!

When configuring an SMPP 3.4 SMSC, if you specify it to use
transceiver mode but also specify a receive-port, not only the
transceiver bind is created, but also a receiver one.
It doesn't seem to create any issues with messaging, but can make you
run out of available allowed sessions against the remote SMSC before
the intended.

I guess that receive-port should be omitted when loading the
configuration if transceiver-mode is enabled, or at least issue a
warning or error if not.

Sample relevant configuration piece:

group                 = smsc
smsc                  = smpp
interface-version     = 34
transceiver-mode      = 1
smsc-id               = "mySmsc"
allowed-smsc-id       = "MYSMSC"
host                  = "xxx.xxx.xxx.xxx"
port                  = xxxx
receive-port          = xxxx
smsc-username         = "myUser"
smsc-password         = "myPasswd"


Sample debug log showing both the transceiver and the receiver binds
being established:
