John Baldwin 5c4309b474 Handle non-dtrace-triggered kernel breakpoint traps in mips.
If DTRACE is enabled at compile time, all kernel breakpoint traps are
first given to dtrace to see if they are triggered by a FBT probe.
Previously if dtrace didn't recognize the trap, it was silently
ignored breaking the handling of other kernel breakpoint traps such as
the debug.kdb.enter sysctl.  This only returns early from the trap
handler if dtrace recognizes the trap and handles it.
