io/channel-tls: plug memory leakage on GSource
This leakage can be seen through test-io-channel-tls:
$ ../configure --target-list=aarch64-softmmu --enable-sanitizers
$ make ./tests/unit/test-io-channel-tls
$ ./tests/unit/test-io-channel-tls
Indirect leak of 104 byte(s) in 1 object(s) allocated from:

SUMMARY: AddressSanitizer: 49143 byte(s) leaked in 184 allocation(s).
The docs for `g_source_add_child_source(source, child_source)` says
"source will hold a reference on child_source while child_source is
attached to it." Therefore, we should unreference the child source at
`qio_channel_tls_read_watch()` after attaching it to `source`. With this
change, ./tests/unit/test-io-channel-tls shows no leakages.
