Check the printk format string against the matching arguments. We have 

this type of checking in the v3 code since ages, but v2 will happily
compile any code with bogus printk format strings and/or parameters.
This can cause real bugs and at least needs to emit a warning, if not
an
error. Go with a warning for now since most of the flagged format
strings are wrong but harmless in a 32-bit x86 environment.
