net: ipa: fix a bug in ipa_endpoint_stop()
In ipa_endpoint_stop(), for TX endpoints we set the number of retries to 0. When we break out of the loop, retries being 0 means we return EIO rather than the value of ret (which should be 0). Fix this by using a non-zero retry count for both RX and TX channels, and just break out of the loop after calling gsi_channel_stop() for TX channels. This way only RX channels will retry, and the retry count will be non-zero at the end for TX channels (so the proper value gets returned).
