drivers: hwspinlock: Fix context initializer build warning

MaureenHelm · jhedberg · commit 8b208b0d5a35 · 2025-11-06T12:31:04.000+02:00
Fixes a build warning in the hwspinlock context initializer macro that
occurs when struct k_spinlock has no members ("warning: excess elements
in struct initializer"). This change is consistent with other struct
k_spinlock initializers in kernel.h.
