BUILD: quic: fix unused variable warning when threads are disabled

Browse Source 
The tree variable was introduced in 3.0 by commit dd58dff1e6
("BUG/MEDIUM: quic: QUIC CID removed from tree without locking") which
was marked for backport. The variable is only used for locks.
Let's just mark the variable __maybe_unused for when the code is
built without threads.

The patch above was marked for backport to 2.7 so this should be
backported wherever the fix was backported.
