Revert "usb: roles: set switch registered flag early on"

This reverts commit 6a902573f2ca7e40fc8714724cf6f0aff0fbb57f which is
commit 634775a752a86784511018a108f3b530cc3399a7 upstream.

The commit it "fixes" was already reverted due to abi breakages, so this
too needs to be reverted in order to fix the build error it causes.
