null_blk: Fix description of the fua parameter

The description of the fua module parameter is defined using
MODULE_PARM_DESC() with the first argument passed being "zoned". That is
the wrong name, obviously. Fix that by using the correct "fua" parameter
name so that "modinfo null_blk" displays correct information.
