rsxx: Restructured DMA cancel scheme.
Before, DMAs would never be cancelled if there was a data stall
or an EEH Permenant failure which would cause an unrecoverable
I/O hang.
The DMA cancellation mechanism has been modified to fix
these issues and allows DMAs to be cancelled during the
above mentioned events.
