Windows: Fix SSL failures on windows with AcceptFilter https none.

The now-stray apr_socket_opt_set(APR_SO_NONBLOCK=On) call was 
originally added with r327872.  The call was harmless on Unix
due to APR's use of non-blocking sockets when implementing timeouts
on that platform, but harmful on Windows since it collided with
APR's different implementation of timeouts on that platform.

1. resets the busy field in the error-ed worker at the end of
   the request instead of at recovery time
2. leaves the lbstatus field alone
3. covers all possible scenarios where the busy field in the
