[MCA] [NFC] Remove unused Index formal from ResourceManager::issueInstruction

[mattd]

Summary

The instruction index was never referenced in the body. Just a minor cleanup.

[mattd]

As a side note, who do we contact to get MCA or LLVM-MCA as a recognized phabricator tag? I'd like to have mca patches hit my inbox differently, and Phabricator tags definitely help me there :)

[andreadb]

Lgtm.

I suggest that @andreadb send a note to the llvm-admin list. Or you can, and CC him.
