Remove CONFIG_RTE_LIBRTE_ICE_RX_ALLOW_BULK_ALLOC with below
consideration:
1. A default Rx path can always be selected by setting a proper
rx_free_thresh value at runtime, see
ice_check_rx_burst_bulk_alloc_preconditions.
2. Its not a big deal to always reserve more space for desc ring.
"ring_size = (uint16_t)(rxq->nb_rx_desc + ICE_RX_MAX_BURST);"
3. Fixes a potential invalid memory access in ice_reset_rx_queue.
If CONFIG_RTE_LIBRTE_ICE_RX_ALLOW_BULK_ALLOC is turned on while
ice_check_rx_burst_bulk_alloc_preconditions return fail.
Below code will have problem.
for (i = 0; i < ICE_RX_MAX_BURST; ++i)
rxq->sw_ring[rxq->nb_rx_desc + i].mbuf = &rxq->fake_mbuf;
Fixes: 50370662b7 ("net/ice: support device and queue ops")
