net/ionic: fix RSS query

[ upstream commit 1df32bfd0317a3c8aed1e91b51ca2aa8317812e4 ]

The routine that copies out the RSS config can't use memcpy() because
'reta_conf->reta' is an array of uint16_t while 'lif->rss_ind_tbl' is
an array of uint8_t. Instead, copy the values individually.

Fixes: 22e7171 ("net/ionic: support RSS")
