C files: cleanup coding style

C files: cleanup coding style

The rasdaemon conding style follows Linux Kernel where it makes sense.

Yet, changes made overtime ended with some coding style non-compliances.

Adjust rasdaemon coding style by using:

   scripts/checkpatch.pl --fix-inplace --strict *.c --ignore PREFER_KERNEL_TYPES

And doing some manual fixups where the script didn't work.
As a bonus, some typos were also fixed on some rasdaemon messages.
