nilfs2: convert __nilfs_msg to integrate the level and format

Bläddra i källkod 
Reduce object size a bit by removing the KERN_<LEVEL> as a separate
argument and adding it to the format string.

Reduce overall object size by about ~.5% (x86-64 defconfig w/ nilfs2)

$ size -t fs/nilfs2/built-in.a | tail -1

new:
$ size -t fs/nilfs2/built-in.a | tail -1
 190971	   8676	     44	 199691	  30c0b	(TOTALS)
