dmaengine: idxd: Add missing idxd cleanup to fix memory leak in remove call

Browse Source 
commit d5449ff1b04dfe9ed8e455769aa01e4c2ccf6805 upstream.

The remove call stack is missing idxd cleanup to free bitmap, ida and
the idxd_device. Call idxd_free() helper routines to make sure we exit
gracefully.
