Liam Mark 6d79bd5bb6 staging: android: ion: Zero CMA allocated memory 
Since commit 204f672255 ("staging: android: ion: Use CMA APIs directly")
the CMA API is now used directly and therefore the allocated memory is no
longer automatically zeroed.

Explicitly zero CMA allocated memory to ensure that no data is exposed to
userspace.

Fixes: 204f672255 ("staging: android: ion: Use CMA APIs directly")
