Roger Pau Monne 7f22201ac8 xen-block: fix reporting of discard feature 
Linux blkfront expects both "discard-granularity" and
"discard-alignment" present on xenbus in order to properly enable the
feature, not exposing "discard-alignment" left some Linux blkfront
versions with a broken discard setup. This has also been addressed in
Linux with:

https://lore.kernel.org/lkml/20210118151528.81668-1-roger.pau@citrix.com/T/#u

Fix QEMU to report a "discard-alignment" of 0, in order for it to work
with older Linux frontends.
