[patch 41/51] dmatest: fix max channels handling

[Greg KH]

2.6.29-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Dan Williams <dan.j.williams@xxxxxxxxx>

commit c56c81abe7e684bc6203632d807303eb765690dc upstream.

The check for reaching max_channels is short circuited by 'continuing'
after successfully adding a channel.

[ Impact: make the 'max_channels' module parameter actually have an effect ]
