UPSTREAM: usb: roles: Improve the fix for a false positive recursive locking complaint

Improve commit fc88bb11 ("usb: roles: add lockdep class key to struct
usb_role_switch") as follows:
* Move the lock class key declaration just above the mutex declaration such
  that the declaration order of these objects matches their initialization
  order.
* Destroy the mutex and lock class key just before these objects are
  freed. This makes it easier to verify that the destruction calls happen
  after the last use of these objects.
* Instead of switching the mutex key to the dynamic lock class key after
  initialization of the mutex has completed, initialize the mutex with the
  dynamic lock class key.
