[PATCH v2 7/7] dm-error: remove unnecessary direct_access() stub

[Ross Zwisler <ross.zwisler@linux.intel.com>]

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.
