lpm: fix SVE bulk lookup loop bound for small bursts
In __rte_lpm_lookup_vec() (SVE), the main loop condition was
for (i = 0; i < n - vl; i += vl)
where n is uint32_t and vl is uint64_t. When n < vl the subtraction
is done in 64-bit unsigned arithmetic and wraps to a very large
value, so the loop does not terminate at the end of the input array.
It reads past the end of ips[] resulting in a segmentation fault.
Rewrite the condition as "i + vl < n" so no unsigned wrap occurs. The
existing tail handling with svwhilelt_b32() covers the remaining
elements, including n == 0.
Fixes: b29ccbea24 ("lpm: use SVE for bulk lookup")
