Andy Shevchenko ad3039362b dmaengine: dmatest: Abort test in case of mapping error 
[ Upstream commit 6454368a80 ]

In case of mapping error the DMA addresses are invalid and continuing
will screw system memory or potentially something else.

[  222.480310] dmatest: dma0chan7-copy0: summary 1 tests, 3 failures 6 iops 349 KB/s (0)
...
[  240.912725] check: Corrupted low memory at 00000000c7c75ac9 (2940 phys) = 5656000000000000
[  240.921998] check: Corrupted low memory at 000000005715a1cd (2948 phys) = 279f2aca5595ab2b
[  240.931280] check: Corrupted low memory at 000000002f4024c0 (2950 phys) = 5e5624f349e793cf
...

Abort any test if mapping failed.
