net/mlx5: fix counter query

Currently, the counter query requires the counter ID should start
with 4 aligned. In none-batch mode, the counter pool might have the
chance to get the counter ID not 4 aligned. In this case, the counter
should be skipped, or the query will be failed.

Skip the counter with ID not 4 aligned as the first counter in the
none-batch count pool to avoid invalid counter query. Once having
new min_dcs ID in the poll less than the skipped counters, the
skipped counters will be returned to the pool free list to use.
