tun: use netdev_alloc_frag() in tun_napi_alloc_frags()
In order to cook skbs in the same way than Ethernet drivers,
it is probably better to not use GFP_KERNEL, but rather
use the GFP_ATOMIC and PFMEMALLOC mechanisms provided by
netdev_alloc_frag().
This would allow to use tun driver even in memory stress
situations, especially if swap is used over this tun channel.
Fixes: 90e33d459407 ("tun: enable napi_gro_frags() for TUN/TAP driver")
