[PATCH v2 1/3] net/ice: fix possible memory leak

[Vladimir Medvedkin]

This patch fixes possible memory leak inside the
ice_hash_parse_raw_pattern() due to the lack of a call to rte_free()
for previously allocated pkt_buf and msk_buf.

Fixes: 1b9c68120a1c ("net/ice: enable protocol agnostic flow offloading in RSS")
