Paul Sauro e2ee665cce usb storage: defer commands until exclusive storage handover completes
A host may send a command after SET_CONFIGURATION while filesystem clients are still acknowledging the storage handover. Previously TEST UNIT READY could report no medium, while other commands could reach storage before exclusive access was granted.

Retain the first CBW until exclusive access is available. Notify the mass-storage class when handover completes, then execute the retained command and keep the OUT endpoint unarmed until its CSW. On BOT reset, discard the retained CBW and accept a new command.

This changes command handling while waiting for ownership. The policy for requesting, preserving and releasing exclusive storage is handled by a separate preparatory patch.
