usb: dwc3: gadget: Clear DEP flags after stop transfers in ep disable

Browse Source 
commit 5aef629704ad4d983ecf5c8a25840f16e45b6d59 upstream.

Ensure that dep->flags are cleared until after stop active transfers
is completed.  Otherwise, the ENDXFER command will not be executed
during ep disable.
