block/gluster: Remove deprecated RDMA protocol handling

Browse source 
GlusterFS+RDMA has been deprecated 8 years ago in commit
0552ff2465 ("block/gluster: deprecate rdma support"):

  gluster volfile server fetch happens through unix and/or tcp,
  it doesn't support volfile fetch over rdma. The rdma code may
  actually mislead, so to make sure things do not break, for now
  we fallback to tcp when requested for rdma, with a warning.

  If you are wondering how this worked all these days, its the
  gluster libgfapi code which handles anything other than unix
  transport as socket/tcp, sad but true.

Besides, the whole RDMA subsystem was deprecated in commit
e9a54265f5 ("hw/rdma: Deprecate the pvrdma device and the rdma
subsystem") released in v8.2.
