Fix BridgeEpollController to handles EAGAIN correctly
When reading/writing proxy FD, if it returns EAGAIN,
BridgeEpollController updates epoll entries to observe specific FD
events. Before updating epoll entries, BridgeEpollController checks if
it really needs to update by comparing |state_| and |last_state_|.
|last_state_| has not been updated correctly so it resulted in wrong
epoll settings and keeps blocking the event loop.
