block: ensure discard_granularity is zero when discard is not supported
Documentation/ABI/stable/sysfs-block states:
What: /sys/block/<disk>/queue/discard_granularity
[...]
A discard_granularity of 0 means that the device does not support
discard functionality.
but this got broken when sorting out the block limits updates. Fix this
by setting the discard_granularity limit to zero when the combined
max_discard_sectors is zero.
Fixes: 3c407dc723bb ("block: default the discard granularity to sector size")
