At first I used GFP_NOIO, but after reviewing gfp.h I convinced myself
GFP_NOWAIT was what I wanted because I was concerned about FS accesses
that aren't restricted in GFP_NOIO.  For some reason, I assumed this was
an issue.  I'm ok with the change and can submit a v2 shortly, after
more tests.  in fact, this will make the change more compliant with the
rest of block layer critical allocations that use GFP_NOIO.

Thanks,
