[mod_scgi] do not reconnect after connect succeeds

apply diff from commit:2eaf42d0 made to mod_fastcgi.c back in 2009

(change is being made for (a bit more) consistency between the modules
 as mod_scgi.c was forked from mod_fastcgi.c a very long time ago, as
 well as to remove call to sleep for 10ms (usleep(10000) from mod_scgi)
