super-intel: ensure suspended region is removed when reshape completes.

A recent commit removed a call to abort_reshape() when IMSM reshape
completed.  An unanticipated result of this is that the suspended
region is not cleared as it should be.
So after a reshape, a region of the array will cause all IO to block.

Re-instate the required updates to suspend_{lo,hi} coped from
abort_reshape().

This is caught (sometimes) by the test suite.

Also fix a couple of typos found while exploring the code.
