Vasily Gorbik fb9b18150e s390/startup: avoid save_area_sync overflow
[ Upstream commit 2835c2ea95 ]

Currently we overflow save_area_sync and write over
save_area_async. Although this is not a real problem make
startup_pgm_check_handler consistent with late pgm check handler and
store [%r0,%r7] directly into gpregs_save_area.
