This release fixes a race condition that can cause waylock to commit a
protocol error and be terminated by the compositor in an edge case.

Due to the fail-safe design of the ext-session-lock-v1 protocol, this is
not a security issue but can make it difficult to recover a locked
session depending on the wayland compositor in use.
