[PATCH] initramfs: prevent initramfs printk message being split by messages from other code.

[Simon Kitching <skitching@apache.org>]

initramfs uses printk without a linefeed, then does some work, then uses printk
to finish the message off. However if some other code does a printk in between,
then the messages get mixed together. Better for each message to be an independent
line...

  Example of problem that this fixes:
    checking if image is initramfs...<7>Switched to high resolution mode on CPU 1
    Switched to high resolution mode on CPU 0
    it is
