Fix typo in inliner badness calculation

[Jan Hubicka]

Hi,
this patch fixes a typo in the way edge badness is calculated I noticed
while verifing the code.

Bootstrapped/regtested x86_64-linux, comitted.

        * ipa-inline.c: Fix type; compute size rather than self_size
        for size of caller function.
