MIPS: traps: Set correct address limit for breakpoints and traps
MIPS: traps: Set correct address limit for breakpoints and traps

When a breakpoint or trap happens when operating in kernel mode but
on users behalf (eg syscall) it is necessary to change the address
limit to KERNEL_DS so any address checking can be bypassed and print
the correct stack trace.
