ubuntu_fs_fio_perf failed due to hardware limitation

[Po-Hsu Lin]

This test was recently added as part of "Kill KT" process (the test white list changed)

Test failed with:
        12/21 10:01:21 ERROR| test:0414| Exception escaping from test:

Even with this NameError fixed [1], this test is still failing with "ERROR: No device specified", further investigation is needed.

Checked the source code, this test is specific to node "ivysaur":

    def initialize(self):
        self.valid_clients = ['ivysaur']
        self.hostname = os.uname()[1]
        if self.hostname == 'ivysaur':
            self.dev = '/dev/sdb'
        else:
            raise error.TestError("ERROR: No device specified")
        self.fio_tests_dir = os.path.join(self.srcdir, 'fs-test-proto', 'fio-tests')

Maybe it can be started on any other node with /deb/sdb present?
