syslog/emerg: fix bug about printing LOG_EMERG log from iob buffer 

The patch is related to: commit 5f7c98b6e1

    drivers/syslog: Remove emergstream implementation and caller

    since emergstream always call syslog_force, but syslog_force is designed
    for the interrupt context, and then doesn't mean any emergency thing.
    On the other hand, emergstream has other bad side effect:
    1.Can't output to file or dev channel
    2.Can't work well with the interrupt buffer
