uml: fix mconsole stop

Bring back the functionality of stopping user mode linux with the help of
mconsole.

[jdike - the bug being fixed is that the mconsole file descriptor is already
set O_NONBLOCK or not, depending on whether we want no blocking (the normal
case) or we want blocking (when an mconsole stop is in effect), so the
MSG_DONTWAIT is redundant in the normal case, and wrong when we want to
block.]
