net: add napi_get_frags_check() helper
This is a follow up of commit 3226b158e67c
("net: avoid 32 x truesize under-estimation for tiny skbs")
When/if we increase MAX_SKB_FRAGS, we better make sure
the old bug will not come back.
Adding a check in napi_get_frags() would be costly,
even if using DEBUG_NET_WARN_ON_ONCE().
