[PATCH 4/4] common/idpf: fix AVX-512 pointer copy on 32-bit

[Bruce Richardson <bruce.richardson@intel.com>]

The size of a pointer on 32-bit is only 4 rather than 8 bytes, so
copying 32 pointers only requires half the number of AVX-512 load store
operations.

Fixes: 5bf87b45b2c8 ("net/idpf: add AVX512 data path for single queue model")
