FROMLIST: driver: bluetooth:btusb: Allow firmware re-download when version matches

Since USB can disconnect at any time, if it disconnects during the
BT firmware download, the BT controller firmware version may still
be updated even without completing the download.

When USB reconnects, the BT host detects the same version as in
the firmware file, which prevents the firmware from being
downloaded again.

Therefore, remove the equality check to ensure that after USB
reconnection, the BT host can still download the firmware.
