dm table: an 'all_blk_mq' table must be loaded for a blk-mq DM device
commit 301fc3f5efb98633115bd887655b19f42c6dfaa8 upstream.
When dm_table_set_type() is used by a target to establish a DM table's
type (e.g. DM_TYPE_MQ_REQUEST_BASED in the case of DM multipath) the
DM core must go on to verify that the devices in the table are
compatible with the established type.
