commit dba599091c191d209b1499511a524ad9657c0e5a upstream.
After a failure during registration of the dma_table (because of the
function being in error state) we free its memory but don't reset the
associated pointer to zero.
When we then receive a notification from firmware (about the function
being in error state) we'll try to walk and free the dma_table again.
Fix this by resetting the dma_table pointer. In addition to that make
sure that we free the iommu_bitmap when appropriate.
