dmaengine: qcom: bam_dma: Fix completed descriptors count
commit f6034225442c4a87906d36e975fd9e99a8f95487 upstream.
One space is left unused in circular FIFO to differentiate
'full' and 'empty' cases. So take that in to account while
counting for the descriptors completed.
Fixes the issue reported here,
