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

Revert commit 12ebcd73e40e09f0dfddf89e465cc0541e0ff8b1, i.e.  [PATCH] uml: run
mconsole "sysrq" in process context on request from Jeff Dike.

a) sysrq may be run when the scheduler is non-functioning

b) the warning I wanted to fix actually came from the fault handler run in
   atomic context.  But I fixed that not to take the semaphore in a separate
   patch.

c) the fault handler is run because of a fault, and that fault was
   unaffected by this patch.
