Call _xcb_wake_up_next_reader from xcb_wait_for_special_event

All functions calling _xcb_conn_wait() must make sure that waiting
readers are woken up when we read a reply or event that they are waiting
for. xcb_wait_for_special_event() did not do so. This adds the missing
call to_xcb_in_wake_up_next_reader().

Fixes deadlock when waiting for a special event and concurrently
processing the display connection queue in another thread.
