minor typo in sys/kern/uipc_socket2.c

[JINMEI Tatuya /神明達哉]

FreeBSD current (and the 5.3 branch) needs the following patch.
Otherwise, it always consumes mbuf cluster for cmsg items even when
unnecessary.

(I should probably file a PR for this, but I currently do not have a
good access to the PR system.  So please forgive me to send this to
the list.)
