dmaengine: idxd: fix memory leak in error handling path of idxd_setup_wqs
commit 3fd2f4bc010cdfbc07dd21018dc65bd9370eb7a4 upstream.
Memory allocated for wqs is not freed if an error occurs during
idxd_setup_wqs(). To fix it, free the allocated memory in the reverse
order of allocation before exiting the function in case of an error.
Fixes: 7c5dd23e57c1 ("dmaengine: idxd: fix wq conf_dev 'struct device' lifetime")
Fixes: 700af3a0a26c ("dmaengine: idxd: add 'struct idxd_dev' as wrapper for conf_dev")
Fixes: de5819b99489 ("dmaengine: idxd: track enabled workqueues in bitmap")
