[Qemu-devel] [PATCH v3 27/27] migration: remove qemu_get_fd method from QEMUFile

["Daniel P. Berrange" <berrange@redhat.com>]

Now that there is a set_blocking callback in QEMUFileOps,
and all users needing non-blocking support have been
converted to QIOChannel, there is no longer any codepath
requiring the qemu_get_fd() method for QEMUFile. Remove it
to avoid further code being introduced with an expectation
of direct file handle access.
