Subject: [PATCH iwl-net] idpf: avoid compiler padding in virtchnl2_ptype struct

Config option in arm random config file is causing the compiler
to add padding. Avoid it by using "__packed" structure attribute
for virtchnl2_ptype struct.

Fixes: 0d7502a9b4a7 ("virtchnl: add virtchnl version 2 ops")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202312220250.ufEm8doQ-lkp@intel.com
