xous: sync: remove rustc_const_stable attribute

xobs · xobs · commit ed1a265dec38 · 2024-10-29T22:43:46.000+08:00
These functions had `#[rustc_const_stable(feature = "const_locks", since = "1.63.0")]` on them because they were originally taken from `no_threads`. with d066dfd these no longer compile. Since other platforms do not have this attribute, remove it. This fixes the build for Xous. Signed-off-by: Sean Cross <sean@xobs.io>
