iotests/291: Stop NBD server

nbd_server_start_unix_socket() includes an implicit nbd_server_stop(),
but we still need an explicit one at the end of the test (where there
follows no next nbd_server_start_unix_socket()), or qemu-nbd will linger
until the test exits.

This will become important when enabling this test to run on FUSE
exports, because then the export (which is the image used by qemu-nbd)
will go away before qemu-nbd exits, which will lead to qemu-nbd
complaining that it cannot flush the bitmaps in the image.
