scoutfs: correctly set new flag in get_blocks

Browse Source 
We weren't setting the new flag in the mapped buffer head.  This tells
the caller that the buffer is newly allocated and needs to be zeroed.
Without this we expose unwritten newly allocated block contents.

fsx found this almost immediately.  With this fixed fsx passes.
