[patch] recv.2: Mention SOCK_SEQPACKET in MSG_TRUNC flag description

[Vladislav Ivanishin <vlad@ispras.ru>]

[-- Type: text/x-patch, Size: 917 bytes --]

unix_seqpacket_recvmsg() calls unix_dgram_recvmsg() which handles
MSG_TRUNC. This has been the case since the support for this flag was
implemented in the latter; the sequential-packet socket type seems to
have been left out from the description by an oversight.
