Subject: ecore_wl: read events only when fd_handler has READ flag.
X-Git-Tag: accepted/tizen/unified/20170719.004634^0

ecore_wl: read events only when fd_handler has READ flag.

fd_handler can be called when WRITE|ERROR flags are set. In these case, we
shouldn't call wl_display_read_event. Otherwise, the main thread will be
deadlock by wl_display_read_event because there is no event to read in
wayland fd.
