i40e: Fix ethtool rx-flow-hash setting for X722



When enabling flow type for RSS hash via ethtool:

ethtool -N $pf rx-flow-hash tcp4|tcp6|udp4|udp6 s|d

the driver would fail to setup this setting on X722
device since it was using the mask on the register
dedicated for X710 devices.

Apply a different mask on the register when setting the
RSS hash for the X722 device.

When displaying the flow types enabled via ethtool:

ethtool -n $pf rx-flow-hash tcp4|tcp6|udp4|udp6

the driver would print wrong values for X722 device.

Fix this issue by testing masks for X722 device in
i40e_get_rss_hash_opts function.

Fixes: eb0dd6e4 ("i40e: Allow RSS Hash set with less than four parameters")
