Fix invalid dereferencing in bmv2/inlining.cpp

[antoninbas]

Thanks to @teverman for reporting this issue. Only some compilers actually complain about this, which is very confusing to me...

[antoninbas]

@teverman I submitted your patch.

[ChrisDodd]

This is a weird one -- the code is clearly illegal so I can't see any compiler not giving an error, but for some reason it works on the versions we normally run with. Is this code dead-code eliminated before the compiler checks it?

[ChrisDodd]

Ah -- I see the propblem now -- this code is not currently built at all; this source file does not appear in Makefile.am. If we need it, it should probably be added to the makefile.

[antoninbas]

That's reassuring... @ChrisDodd and @mbudiu-vmw should we remove this code then if it is not used?

[mihaibudiu]

The file is probably checked-in by mistake; let's delete it.

[teverman]

So it's breaking in our environment because it just globs all the cpp files from the bmv2 directory.

PR #515 removes these files, as @mbudiu-vmw suggested
