Summary

Flag when we have a pending TUR. Don't schedule another one when we
have one pending. Otherwise, we can race and send two, which is
wasteful in close proximity. It can also cause the acaquire/release
count for TUR to be > 1, which is undexpected.

I have tried this diff on r331284 and it still panic when I plug my Transcend microSD reader in. The stack backtrace is exactly same with what I've supplied in the mailing list.
