oops handling: ensure that any oops is flushed to the mtdoops console
This used to work unpatched with older kernels, during the development
phase of mtdoops. Before commit e3e8a75d2acfc61ebf25524666a0a2c6abb0620c
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.
