Bluetooth: hci_sync: Fix Opcode prints in bt_dev_dbg/err

[ Upstream commit 530886897c789cf77c9a0d4a7cc5549f0768b5f8 ]

Printed Opcodes may be missing leading zeros:

	Bluetooth: hci0: Opcode 0x c03 failed: -110

Fix this by always printing leading zeros:

	Bluetooth: hci0: Opcode 0x0c03 failed: -110

Fixes: d0b137062b2d ("Bluetooth: hci_sync: Rework init stages")
Fixes: 6a98e3836fa2 ("Bluetooth: Add helper for serialized HCI command execution")
