oops handling: ensure that any oops is flushed to the mtdoops console

Browse source 
This used to work unpatched with older kernels, during the development
phase of mtdoops.  Before commit e3e8a75d2a
a space was printed with console_loglevel set to 15, which probably
flushed the oops message as a side effect.

This is another patch from the Nokia N810 kernel.
