kernel: nfsd: release layout stid on setlease failure

A flaw was found in the Linux kernel's Network File System Daemon nfsd. When a setlease operation fails, the system prematurely releases a layout state identifier. An attacker could exploit this by triggering the failure, leading to a use-after-free vulnerability. This could result in a system...
