dma-contiguous: Retrun 'zero' pfn in case of error

Chintan Pandya authored Apr 18, 2014 and Laura Abbott committed Apr 24, 2014

When CMA allocator gets error return from the page
allocator framework, except for the -EBUSY case, it
will bail out. Caller depends on the 'pfn' for
confirming allocation successful or not. Return 0
for those error case.
