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'.
At device creation, memory is allocated for both 'batch_comp_ring' and
'batch_idx_ring' simultaneously. Calling free only on 'batch_idx_ring'
meant the first half of this memory was not being free'd, leading to the
memleak.
This patch fixes this memleak by calling free on 'batch_comp_ring' which
will free the memory for both rings.
