kernel: dm ioctl: prevent potential spectre v1 gadget

A vulnerability was found in the Linux kernel's dm-ioctl interface in the lookupioctl function, which accepts a user-provided cmd value that is used to index the ioctls array directly. This issue could lead to an out-of-bounds access if the CPU speculatively executes the array access before cmd i...
