[PATCH 08/12] net/qede/base: fix build with GCC 12

[David Marchand]

GCC raises the following warning:

In function ‘_mm256_storeu_si256’,
    inlined from ‘rte_mov32’ at
        ../lib/eal/x86/include/rte_memcpy.h:320:2,
    inlined from ‘rte_mov128’ at
        ../lib/eal/x86/include/rte_memcpy.h:342:2,

      |                              ^~~~~~~~~~

Since this code is in the base driver, waive the check until the base
driver is fixed by the relevant people.
