network - Fix race in accept()

* Fix a race where a socket undergoing an accept() was not being
  referenced soon enough, resulting in a window of opportunity for
  the kernel to attempt to free it if the tcp connection resets
  before userland can finish the accept.

  This resulted in an assertion panic.
