binder: use EPOLLERR from eventpoll.h
Use EPOLLERR instead of POLLERR to make sure it is cast to the correct
__poll_t type. This fixes the following sparse issue:
drivers/android/binder.c:5030:24: warning: incorrect type in return expression (different base types)
drivers/android/binder.c:5030:24: expected restricted __poll_t
drivers/android/binder.c:5030:24: got int
Fixes: f88982679f54 ("binder: check for binder_thread allocation failure in binder_poll()")
