Reverting 80476 and 80479. This solution is flawed and causes some weird
collateral damages that need further investigation. All programs running with
wayland engines are consuming 100% CPU.

ecore-wayland: Fix monitoring ECORE_FD_WRITE defaultly on
   wayland display fd lead to 100% cpu usage

  In ecore_wl_init(), adding wayland display fd with ECORE_FD_WRITE
  flag make CPU usage 100%. The proper way to monitor the ECORE_FD_WRITE
  is when the wl_display_flush() return value < 0 and errno == EAGAIN.
  And if wl_display_flush() return, we remove ECORE_FD_WRITE flag from
  the display fd.
