Can we get a `warning' string literal in that message, so I notice it when
grepping for compiler warnings?

... Ah, there already exists a warn() routine, so let's use it.

Subject: modpost: Use warn() for announcing section mismatches

modpost: Use warn() for announcing section mismatches, for easy grepping for

Also change an existing call from fprintf() to warn() while we're at it.
