Revert "dm: make sure dm_table is binded before queue request" 

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7FI78



--------------------------------

This reverts commit 90d1a836.

It's not proper to just abort IO when the map is not ready.
So revert this and requeue IO to keep consistent with the community.
