mailbox: qcom-ipcc: Remove redundant mbox_controller_unregister() on probe failure

qcom_ipcc_probe() registers the mailbox controller via
devm_mbox_controller_register(), which automatically calls
mbox_controller_unregister() through devres when the device is removed
or probe fails. If devm_request_irq() subsequently fails, the
err_req_irq: label also manually calls mbox_controller_unregister(),
resulting in a double call that corrupts the global mailbox controller
list and causes a kernel panic.

Remove the redundant manual call and rely on devres for cleanup.
