Since we save the interrupt mask in the trapframe when we get a trap, we
might restore the wrong mask when we switch CPUs. Since we should be
running with the proper mask when we enter $syscall_return, simply save
the proper mask into the trapframe such that we restore the right interrupt
mask later on.
