dmaengine: idxd: Fix a possible NULL pointer dereference
'device_driver_attach()' dereferences its first argument (i.e. 'alt_drv')
so it must not be NULL.
Simplify the error handling logic about NULL 'alt_drv' in order to be
more robust and future-proof.
Fixes: 568b2126466f ("dmaengine: idxd: fix uninit var for alt_drv")
Fixes: 6e7f3ee97bbe ("dmaengine: idxd: move dsa_drv support to compatible mode")
