[Qemu-stable] [PATCH 053/113] gluster: Fix blockdev-add with server.N.type=unix

[Michael Roth]

From: Kevin Wolf <address@hidden>

The legacy command line interface gets the socket path from an option
called 'socket'. QAPI in contract uses SocketAddress, where the
corresponding option is called 'path'.

Fix the gluster block driver to accept both 'socket' and 'path', with
'path' being the preferred syntax.
