locking/local_lock: Add missing owner initialization
[ Upstream commit d8bbd97ad0b99a9394f2cd8410b884c48e218cf0 ]
If CONFIG_DEBUG_LOCK_ALLOC=y is enabled then local_lock_t has an 'owner'
member which is checked for consistency, but nothing initialized it to
zero explicitly.
The static initializer does so implicit, and the run time allocated per CPU
storage is usually zero initialized as well, but relying on that is not
really good practice.
