block: temporarily disable discard granularity

Commit 86b37281411cf1e9bc0a6b5406c45edb7bd9ea5d adds a check for
misaligned stacking offsets, but it's buggy since the defaults are 0.
Hence all dm devices that pass in a non-zero starting offset will
be marked as misaligned amd dm will complain.

A real fix is coming, in the mean time disable the discard granularity
check so that users don't worry about dm reporting about misaligned
devices.
