[PATCH 07/12] net/ice/base: fix build with GCC 12

[David Marchand]

GCC 12 raises the following warning:

../drivers/net/ice/base/ice_switch.c: In function ‘ice_add_sw_recipe’:
../drivers/net/ice/base/ice_switch.c:7219:61: error: writing 1 byte
        into a region of size 0 [-Werror=stringop-overflow=]
 7219 |         buf[recps].content.lkup_indx[i + 1] = entry->fv_idx[i];
      |         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~
In file included from ../drivers/net/ice/base/ice_controlq.h:8,
                 from ../drivers/net/ice/base/ice_type.h:54,
                 from ../drivers/net/ice/base/ice_common.h:8,
                 from ../drivers/net/ice/base/ice_switch.h:8,
                 from ../drivers/net/ice/base/ice_switch.c:5:
../drivers/net/ice/base/ice_adminq_cmd.h:744:12: note: at offset 5
        into destination object ‘lkup_indx’ of size 5
  744 |         u8 lkup_indx[5];
      |            ^~~~~~~~~

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