Amelie Delaunay b35b82e664 usb: dwc2: drd: reset current session before setting the new one ...

[ Upstream commit 1ad707f559f7cb12c64f3d7cb37f0b1ea27c1058 ]

If role is changed without the "none" step, A- and B- valid session could
be set at the same time. It is an issue.
This patch resets A-session if role switch sets B-session, and resets
B-session if role switch sets A-session.
Then, it is possible to change the role without the "none" step.
