module: check kernel param length at compile time, not runtime
The kparam code tries to handle over-length parameter prefixes at runtime. Not only would I bet this has never been tested, it's not clear that truncating names is a good idea either. So let's check at compile time. We need to move the #define to moduleparam.h to do this, though. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
