ipv4: fix ineffective source address selection
[ Upstream commit 0a7e22609067ff524fc7bbd45c6951dd08561667 ] When sending out multicast messages, the source address in inet->mc_addr is ignored and rewritten by an autoselected one. This is caused by a typo in commit 813b3b5db831 ("ipv4: Use caller's on-stack flowi as-is in output route lookups").
