kfdtest: Add log message in KFDEvictTest

Map failures happen in AllocBuffers function when there
isn't enough space to move BO to vram. In such cases, the
function retries allocation/map until successful to continue
testing eviction and restore.

Print a message in KFDEvictTest when this happens to correlate
to the message seen in the kernel log.
