[PATCH] net/i40e: fix raw flow item validation

[Ciara Loftus]

Commit c138a6c3bd0a ("net/i40e: validate raw flow items before
dereferencing") rejected raw flow items when spec and mask length
fields differ, intending to prevent out-of-bounds pattern access.

This breaks flows using the default rte_flow_item_raw_mask, which
sets mask.length to 0xffff regardless of the spec pattern size. Remove
the erroneous check.
