test/dma: fix missing checks for device capacity

For some DMA HW devices, e.g. those using the idxd driver, the maximum
burst size is configurable, which can lead to test failures if the value
is set too small. Add explicit check for this to give reasonable error
messages for devices which need their config adjusted.
