[PATCH] net/nfp: fix bad copy paste in nfp_net_flow_merge_ipv6

[PATCH] net/nfp: fix bad copy paste in nfp_net_flow_merge_ipv6

[Bulatov Mark]

The nfp_net_flow_merge_ipv6() function contains two blocks: the first
iterates over ipv6->src_ipv6_mask, and the second over ipv6->src_ipv6.
However, in the first block, ipv6->src_ipv6 is passed as an argument
to sizeof() instead of ipv6->src_ipv6_mask.

Fixing this by replacing ipv6->src_ipv6 with ipv6->src_ipv6_mask.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: 9f27cb8892 ("net/nfp: support IPv6 flow item")
