os-brick _rescan_multipath has wrong parameter

[Hyun Ha]

_rescan_multipath has wrong parameter of multipath rescan.

os-brick/initiator/connector.py
   def _rescan_multipath(self):
        self._run_multipath('-r', check_exit_code=[0, 1, 21])

the result of multipath rescan is "multipath - r", not the right format "multipath -r"

This is the same bug on Cinder as below:

Removing target just because brick does not block the Cinder Kilo release.

This actually appears to have been fixed in both places, but added os-brick here since (I think) that's what this was originally intended for and to provide the linkage.

Guessing these can just be closed.

This should be closed. It's already been fixed in os-brick
