net: systemport: Fix NULL pointer dereference in bcm_sysport_fini_rx_ring()
If allocation of priv->rx_cbs fails during bcm_sysport_init_rx_ring(),
error unwinding in bcm_sysport_open() calls bcm_sysport_fini_rx_ring().
Without checking if priv->rx_cbs is non-NULL, bcm_sysport_fini_rx_ring()
dereferences priv->rx_cbs, resulting in a NULL pointer dereference.
Add a check for !priv->rx_cbs at the beginning of
bcm_sysport_fini_rx_ring(), matching bcm_sysport_fini_tx_ring().
