[PATCH 7/7] dm-error: remove unnecessary direct_access() stub

From: Ross Zwisler
Date: Fri May 25 2018 - 07:59:17 EST


This stub was added so that we could use dm-error with
DM_TYPE_DAX_BIO_BASED mode devices. That mode and the transition issues
associated with it no longer exist, so we can remove this dead code.
