CMA multicast joins for the IPoIB port space need to use the same
component mask used by the ipoib driver.  Otherwise, it's possible for
the CMA to create a group to which a join made by ipoib will fail, or
vise-versa.  Some of the component mask fields set by ipoib weren't
set by the CMA, fix that.
