ARM: 8475/1: SWP emulation: Restore original *data when failed
__user_swpX_asm maybe failed in first STREX operation, emulate_swpX
will try again, but the *data has been changed in first time. which

This patch is to fix this issue. When STREX succeed, change the *data.
if it fail, *data is not changed.
