Ard Biesheuvel d173aee570 efi/libstub: Free correct pointer on failure 
commit 06d39d79cb upstream.

cmdline_ptr is an out parameter, which is not allocated by the function
itself, and likely points into the caller's stack.

cmdline refers to the pool allocation that should be freed when cleaning
up after a failure, so pass this instead to free_pool().

Fixes: 42c8ea3dca ("efi: libstub: Factor out EFI stub entrypoint ...")
