[ARM] 5416/1: Use unused address in v6_early_abort

The target of the strex instruction to clear the exlusive monitor
is currently the top of the stack.  If the store succeeeds this
corrupts r0 in pt_regs.  Use the next stack location instead of
the current one to prevent any chance of corrupting an in-use
address.
