[PATCH BlueZ 1/2] btio: Remove POLLOUT check from bt_io_bcast_accept

[Iulia Tanasescu <iulia.tanasescu@xxxxxxx>]

For the Broadcast Sink defer setup scenario, there is no need to check
for the POLLOUT event on the PA sync socket before calling "read" to
issue the Create BIG sync command. This check has been inherited from
unicast, but it is unnecessary for broadcast, since currently after
accept and read, the event to signal BIG sync established is G_IO_IN.
