mi: Hush an almost certainly bogus warning 

In file included from ../mi/miexpose.c:83:
../mi/miexpose.c: In function ‘miHandleExposures’:
../include/regionstr.h:174:22: warning: ‘expBox.y2’ may be used uninitialized in this function [-Wmaybe-uninitialized]
     (_pReg)->extents = *(_pBox);
     ~~~~~~~~~~~~~~~~~^~~~~~~~~~
../mi/miexpose.c:139:12: note: ‘expBox.y2’ was declared here
     BoxRec expBox;
            ^~~~~~

etc. It's initialized if (extents), and then only read if (extents),
but gcc doesn't seem to figure that out. Whatever, bzero it to be
explicit.
