ACPI: acpi_watchdog: use LIST_HEAD for stack-allocated list

Replace the separate declaration of 'resource_list' and subsequent
INIT_LIST_HEAD() call with LIST_HEAD(), which declares and initializes
the list head in one idiomatic step. This reduces code verbosity and
aligns with common kernel coding patterns, without functional change.
