dm raid: remove unnecessary discard limits for raid0 and raid10
Commit 29efc390b946 ("md/md0: optimize raid0 discard handling") and
commit d30588b2731f ("md/raid10: improve raid10 discard request")
remove MD raid0's and raid10's inability to properly handle large
discards. So eliminate associated constraints from dm-raid's support.
