WARNING: unused variadic paramters.

[Cvikli]

Hey @maleadt,
I get these warning messages after using the julia nightly builds:

WARNING: method definition for attribute at /home/user/.julia/packages/CUDA/DfvRa/lib/cudadrv/pool.jl:79 declares type variable T but does not use it.
WARNING: method definition for attribute! at /home/user/.julia/packages/CUDA/DfvRa/lib/cudadrv/pool.jl:90 declares type variable T but does not use it.
WARNING: method definition for #cudacall#42 at /home/user/.julia/packages/CUDA/DfvRa/lib/cudadrv/execution.jl:131 declares type variable N but does not use it.
WARNING: method definition for #bitonic_sort!#3 at /home/user/.julia/packages/CUDA/DfvRa/src/sorting.jl:836 declares type variable T but does not use it.

Can you clean these little warnings?

Please don't disregard the bug template.

Always ensure you're using the latest version of CUDA.jl, and if possible, please
check the master branch to see if your issue hasn't been resolved yet.

Doing so would have shown that these have been fixed already: #1585.
