scsi: qedi: Initialize callback state before registration
qedi_get_protocol_tlv_data() can be called asynchronously by QED after
qedi_ops->register_ops(). It takes stats_lock and reads ll2_mtu, but
__qedi_probe() currently registers the callback before initializing the
mutex and assigning the default MTU on the normal probe path.
Initialize the callback-visible state before registering qedi_cb_ops. Keep
the recovery path from reinitializing state because it reuses the existing
qedi context.
