Description
Hi! I just tried to get the backend of a CuArray as follows, which causes a stack overflow. Am I using it correctly?
using CUDA
using KernelAbstractions
get_backend(cu(rand(3)))
ERROR: StackOverflowError:
Stacktrace:
[1] get_backend(A::CuArray{Float32, 1, CUDA.Mem.DeviceBuffer}) (repeats 79984 times)
@ KernelAbstractions ~/.julia/packages/KernelAbstractions/I7qXs/src/KernelAbstractions.jl:355
Julia 1.8.0
CUDA 4.0.1
KernelAbstractions 0.9.0

Research direction
Start with src/KernelAbstractions.jl:355 and reproduce get_backend(cu(rand(3))) using the Julia, CUDA, and KernelAbstractions versions reported in the issue. Trace why get_backend repeats until StackOverflowError, then verify that the call returns the expected backend without recursion.
