[LibClang] Fix clang_getCursorAvailability

[skalinichev]

Summary

Make it report correct availability kind for deleted methods

[klimek]

Wow, that goes a long while back into:
http://reviews.llvm.org/rL111858
where the current case was handled somewhere else, and seems to have been refactored into a place where it's incorrect.

Looks good.

Ping? Can someone please submit this upstream?

Submitted as r248596. Sergey, if you plan to work on libclang more, please
get commit access (it's easy :) Thx
