uml: Don't consult current to find the proc_mnt in mconsole_proc
Inspection of the control flow reveals that mconsole_proc is either
called from mconsole_stop called from mc_work_proc or from
mc_work_proc directly. The function mc_work_proc is dispatched to a
kernel thread with schedule_work.
All of the threads that run dispatched by schedule_work are in the
init pid namespace.
So make the code clearer and by using init_pid_ns instead of
task_active_pid_ns(current).
