This was in fact fixed earlier this week by commit 2e47c53503eb ("USB:
usbtmc: fix probe error path") in Greg's usb-linus branch.

The current error label is indeed confusingly named, but that can be
addressed by a follow-on clean-up patch. Note that naming error labels
after what they do (e.g. err_remove_capability) is generally preferred.
