Apply a workaround for problem fixed in sys/socketvar.h rev. 1.137. We
can't MFC socketvar.h since it will break ABI between kernel and several
modules. This workaround saves sb_state in local variable and restores
it after bzero().

Original commit log of socketvar.h and problem description:
  Move sb_state to the beginning of structure, above sb_startzero member.
  sb_state shouldn't be erased, when socket buffer is flushed by sorflush().

  When sb_state was bzero'ed, a recently set SBS_CANTRCVMORE flag was cleared.
  If a socket was shutdown(SHUT_RD), a subsequent read() would block on it.
