[PATCH] uml: run mconsole "sysrq" in process context

Things are breaking horribly with sysrq called in interrupt context.  I want
to try to fix it, but probably this is simpler.  To tell the truth, sysrq is
normally run in interrupt context, so there shouldn't be any problem.

There's also a warning from the fault handler because it's run in atomic
context (I have a patch for that, only I deferred it).  This is why I'm doing
this.
