The btt-pad-compat.sh test was failing for me because the namespace it was creating was 32 MiB in size, but it was trying to do 64 MiB worth of I/O using xxd. This happened because when we created the namespace we didn't specify a size, and in nfit_test we could have hit either a 64 MiB or a 32 MiB region. Vishal happened to be getting the 64 MiB region, and I happened to get the 32 MiB. Fix this by explicitly requesting a namespace size of 64 MiB.
