Lack of memory can cause nfs_lock_context allocation failures in unlock
paths, triggering NULL pointer dereference upon unlock completion.
Additionally, failed nfs_open_context acquisition may lead to similar
vulnerabilities. Proper error handling during lock/unlock data
initialization prevents critical faults.
