hw/s390x/3270-ccw: avoid taking address of fields in packed struct

Compiling with GCC 9 complains

hw/s390x/3270-ccw.c: In function ‘emulated_ccw_3270_cb’:
hw/s390x/3270-ccw.c:81:19: error: taking address of packed member of ‘struct SCHIB’ may result in an unaligned pointer value [-Werror=address-of-packed-member]
   81 |         SCSW *s = &sch->curr_status.scsw;
      |                   ^~~~~~~~~~~~~~~~~~~~~~

This local variable is only present to save a little bit of
typing when setting the field later. Get rid of this to avoid
the warning about unaligned accesses.
