mempool/octeontx2: fix possible arm64 ABI break

Browse Source 
Since direct register access is used in npa_lf_aura_op_alloc_bulk()
use __rte_noinline instead of __rte_always_inline to preserve ABI.
Based on the compiler npa_lf_aura_op_alloc_bulk might be inlined
differently which may lead to undefined behaviour due to handcoded
asm.
