powerpc: Fix kernel log of oops/panic instruction dump
powerpc: Fix kernel log of oops/panic instruction dump

A kernel oops/panic prints an instruction dump showing several
instructions before and after the instruction which caused the
oops/panic.

The code intended that the faulting instruction be enclosed in angle
brackets, however a bug caused the faulting instruction to be
interpreted by printk() as the message log level.

To fix this, the KERN_CONT log level is added before the actual text of
the printed message.
