icnss: Consolidate logging message

Currently the code makes liberal use of macros that print a log message
(with pr_err or pr_debug) and then passes the same string on to the
IPC logging mechanism. The problem is that it doesn't actually end up
being the same string in the binary. Using pr_err or one of its friends
appends the KERN_* code to the front of the string with the pre-processor
and the IPC logger just uses the passed in string. Every string used by
the macros ends up appearing twice in the binary, once with KERN_*
prepended and the other not.

This change fix this duplication issue by appending KERN_* to the front
of the IPC logger.
