Alexandre Bounine 7bfa5bfd88 rapidio/tsi721_dma: fix failure to obtain transaction descriptor ...

commit 0193ed8225e1a79ed64632106ec3cc81798cb13c upstream.

This is a bug fix for the situation when function tsi721_desc_get() fails
to obtain a free transaction descriptor.

The bug usually results in a memory access crash dump when data transfer
scatter-gather list has more entries than size of hardware buffer
descriptors ring.  This fix ensures that error is properly returned to a
caller instead of an invalid entry.

This patch is applicable to kernel versions starting from v3.5.
