  freeswitch: Avoid dangling socket structs in reactor

Should reactor_del_reader() ever fail, retry it using index "-1" in
order to guarantee removal of the file descriptor from the EPOLL
controller.

Also fix several occurences of bad 3rd parameter (IO_WATCH_READ instead
of IO_FD_CLOSING, which was probably the intended argument).

(cherry picked from commit 26a9e3a269f9e9b13c5de04422d4efd79ba27b54)
