[PATCH v3 9/9] objtool/klp: Fix line numbers in Module.symvers parse errors

[Josh Poimboeuf]

read_exports() reports the offending line number when it fails to parse
Module.symvers.  The counter is initialized to 1 but never incremented,
so every error blames line 1 regardless of where the bad line is.
