We have just arrived as:

migration.c: qemu_migrate()
  ....
  s = migrate_init() <- puts it to NULL
  ....
  {tcp,unix}_start_outgoing_migration ->
     socket_outgoing_migration
        migration_channel_connect()
	   sets to_dst_file

if tls is enabled, we do another round through
migrate_channel_tls_connect(), but we only set it up if there is no
error.  So we don't need the assignation.  I am removing it to remove
in the follwing patches the knowledge about MigrationState in that two
files.

Historically the migration data channel has only needed to be
unidirectional. Thus the 'exec:' protocol was requesting an
I/O channel with O_RDONLY on incoming side, and O_WRONLY on
the outgoing side.

This is fine for classic migration, but if you then try to run
TLS over it, this fails because the TLS handshake requires a
bi-directional channel.
