gluster: stop using .bdrv_needs_filename

Browse Source 
The gluster protocol driver used to parse URIs (filenames) but was
extended with a richer JSON syntax in commit 6c7189bb29
("block/gluster: add support for multiple gluster servers"). The gluster
drivers that have JSON parsing set .bdrv_needs_filename to false.

The gluster+unix and gluster+rdma drivers still to require a filename
even though the JSON parser is equipped to parse the same
volume/path/sockaddr details as the URI parser. Let's allow JSON parsing
for these drivers too.

Note that the gluster+rdma driver actually uses TCP because RDMA support
is not available, so the JSON server.type field must be "inet".

Drop .bdrv_needs_filename since both the filename and the JSON parsers
can handle gluster+unix and gluster+rdma. This change is in preparation
for eventually removing .bdrv_needs_filename across the entire codebase.
