  Issue:
When define CONFIG_RTE_LIBTRE_I40E_RX_ALLOW_BULK_ALLOC as n in config file,
there will be a build error:
'i40e_recv_pkts_bulk_alloc' undeclared 

Now DPDK i40e PMD use the Macro variable to choose whether to define the
related bulk recv functions, but for selection of the RX function,PMD only
depends on a C variable, which will cause the inconsistency and lead to the
build error which will tell us the bulk recv function is not defined.
 
Fixes: 8e109464 (i40e: allow vector Rx and Tx usage)
