Deallocate the vectors allocated only in the C interface

For some batched routines, we need a vector of `onemklTranspose`, `onemklDiag`, or `onemklSide`.
I allocate them in the C interface with the function [`convert`](https://github.com/JuliaGPU/oneAPI.jl/blob/master/deps/onemkl_prologue.cpp#L19-L35) but it's never deallocated after the call to the oneMKL routine, like [here](https://github.com/JuliaGPU/oneAPI.jl/blob/master/deps/src/onemkl.cpp#L3102) with `convert(uplo, group_count)`.

Start in deps/onemkl_prologue.cpp, where convert allocates vectors for onemklTranspose, onemklDiag, or onemklSide, then inspect its callers in deps/src/onemkl.cpp, including the call near line 3102. Done means vectors allocated only for the C interface are deallocated after the corresponding oneMKL routine calls.
