No lock in reject

[AgrimPrasad]

#318 and #327 added locks for ack/nack but there's still no lock for reject:

amqp/channel.go

Lines 1582 to 1587 in 27835f1

	func (ch *Channel) Reject(tag uint64, requeue bool) error {
	return ch.send(&basicReject{
	DeliveryTag: tag,
	Requeue: requeue,
	})
	}

Is there any reason for this or is it okay if I create a PR to fix this?

No particular reason. Please submit a PR.

[AgrimPrasad]

Sure, created #375
