lu_instance doesn't work for Metal.jl array

[ctessum]

For example:

using Metal
using LinearAlgebra
using ArrayInterface

x = MtlArray(rand(Float32, 3, 3))
lu(x) # This works.
ArrayInterface.lu_instance(rand(Float32, 3, 3)) # This works.
ArrayInterface.lu_instance(x) # This fails.

This is the error message:
