poll_wait: kill the obsolete wait_address check
This check is historical and no longer needed, wait_address is never NULL.
These days we rely on the poll_table->_qproc check. NULL if select/poll
is not going to sleep, or it already has a data to report, or all waiters
have already been registered after the 1st iteration.
However, poll_table *p can be NULL, see p9_fd_poll() for example, so we
can't remove the "p != NULL" check.
