block/gluster: Remove deprecated RDMA protocol handling
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.
