[PATCH 1/3] net/ipv4/inet_timewait_sock: Fix inconsistent comments

[sjpark]

From: SeongJae Park <sjpark@xxxxxxxxx>

Commit ec94c2696f0b ("tcp/dccp: avoid one atomic operation for timewait
hashdance") mistakenly erased a comment for the second step of
`inet_twsk_hashdance()`.  This commit restores it for better
readability.
