unpack-trees: remove outdated description for verify_clean_submodule
The function verify_clean_submodule() learned to verify if a submodule
working tree is clean in a7bc845a9a (unpack-trees: check if we can
perform the operation for submodules, 2017-03-14), but the commented
description above it was not updated to reflect that, such that this
description has been outdated since then.
Since Git has now learned to optionnally recursively check out
submodules during a superproject checkout, remove this outdated
description.
