block/replication: Remove protocol_name field

The protocol_name field is used when selecting a driver via protocol
syntax (i.e. <protocol_name>:<filename:options:...>). Drivers that are
only selected explicitly (e.g. driver=replication,mode=primary,...)
should not have a protocol_name.

This patch removes the protocol_name field from the brdv_replication
structure so that attempts to invoke this driver using protocol syntax
will fail gracefully:

  $ qemu-img info replication:foo
  qemu-img: Could not open 'replication:': Unknown protocol 'replication'
