i40e: fix overflow

Browse Source 
The array 'ptype_table' was defined in depth of 'UINT8_MAX' which
is 255, while the querying index could be from 0 to 255. The issue
can be fixed with expanding the array to one more element.

Fixes: 9571ea0284 ("i40e: replace some offload flags with unified packet type")
