commit a409e919ca321cc0e28f8abf96fde299f0072a81 upstream.

The idxd_cleanup() helper cleans up perfmon, interrupts, internals and
so on. Refactor remove call with the idxd_cleanup() helper to avoid code
duplication. Note, this also fixes the missing put_device() for idxd
groups, enginces and wqs.

Fixes: bfe1d56091c1 ("dmaengine: idxd: Init and probe for Intel data accelerators")
