ARM: dma-mapping: fix GFP_ATOMIC macro usage

commit 10c8562f932d89c030083e15f9279971ed637136 upstream.

GFP_ATOMIC is not a single gfp flag, but a macro which expands to the other
flags and LACK of __GFP_WAIT flag. To check if caller wanted to perform an
atomic allocation, the code must test __GFP_WAIT flag presence. This patch
fixes the issue introduced in v3.6-rc5
