net/mosquitto: Update to 2.0.10 and solve NULL pointer dereference

https://github.com/eclipse/mosquitto/blob/d5ecd9f5aa98d42e7549eea09a71a23eef241f31/ChangeLog.txt

This release fixes a DoS vulnerability:

If an authenticated client connected with MQTT v5 sent a malformed CONNACK message to the broker a NULL pointer dereference occurred, most likely resulting in a segfault.

Other changes since 2.0.8:

Set receive-maximum to not exceed the -C message count in mosquitto_sub and mosquitto_rr, to avoid potentially lost messages.
Fix TLS-PSK mode not working with port 8883.
Fix possible socket leak. This would occur if a client was using mosquitto_loop_start(), then if the connection failed due to the remote server being inaccessible they called mosquitto_loop_stop(, true) and recreated the mosquitto object.
If an empty or invalid CA file was provided to the client library for verifying the remote broker, then the initial connection would fail but subsequent connections would succeed without verifying the remote broker certificate.
If an empty or invalid CA file was provided to the broker for verifying the remote broker for an outgoing bridge connection then the initial connection would fail but subsequent connections would succeed without verifying the remote broker certificate.
Fix encrypted bridge connections incorrectly connecting when bridge_cafile is empty or invalid.
Fix tls_version behaviour not matching documentation.
Fix messages to $ prefixed topics being rejected.
Fix QoS 0 messages not being delivered when max_queued_bytes was configured.
Fix bridge increasing backoff calculation.
Improve handling of invalid combinations of listener address and bind interface configurations.
Fix max_keepalive option not applying to clients connecting with keepalive
Fix encrypted connections incorrectly connecting when the CA file passed to mosquitto_tls_set() is empty or invalid. set to 0.
