[PATCH v2 2/3] dma/idxd: fix memory leak due to free on incorrect pointer

[Kevin Laatz <kevin.laatz@intel.com>]

During PCI device close, any allocated memory needs to be free'd.
Currently, one of the free's is being called on an incorrect idxd_dmadev
struct member, namely 'batch_idx_ring', causing a memleak from the
pointer that should have been free'd.
This patch fixes this memleak by calling free on the correct pointer.
