[PATCH 1/1] target/arm: Fix arithmetic underflow in SETM instruction

[Ido Plat <ido.plat1@ibm.com>]

Pass the stage size to step function callback,
otherwise do_setm would hang when size is larger then page size because stage size would underflow.
This fix changes do_setm to be more inline with do_setp.
