BUG/MINOR: quic: Fix memory leak in quic_deallocate_dghdlrs()

When deallocating the QUIC datagram handlers, the per-thread buffer
allocated inside quic_dghdlrs[i].buf.buffer was missing a free().
This led to a memory leak on exit or reload.

Fix this by freeing each thread buffer before releasing the main
quic_dghdlrs array.
