Subject: [PATCH] dmaengine: idxd: Refactor remove call with idxd_cleanup()
helper

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.
