dm raid: remove unnecessary discard limits for raid10
Notice: this object is not reachable from any branch.
Commit 828d14fd7a6cf ("md/raid10: improve raid10 discard request")
removes raid10's inability to properly handle large discards. So
eliminate associated constraint from dm-raid's raid10 support.
