Christophe JAILLET b3c7b5d08e dmaengine: idxd: Fix the error handling path in idxd_cdev_register() ...

[ Upstream commit aab08c1aac01097815fbcf10fce7021d2396a31f ]

If a call to alloc_chrdev_region() fails, the already allocated resources
are leaking.

Add the needed error handling path to fix the leak.
