fs/lock: Don't allocate file_lock in flock_make_lock().
Two functions, flock syscall and locks_remove_flock(), call flock_make_lock(). It allocates struct file_lock from slab cache if its argument fl is NULL. When we call flock syscall, we pass NULL to allocate memory for struct file_lock. However, we always free it at the end by locks_free_lock(). We need not allocate it and instead should use a local variable as locks_remove_flock() does. Also, the validation for flock_translate_cmd() is not necessary for locks_remove_flock(). So we move the part to flock syscall and make flock_make_lock() return nothing.
