[SCSI] dm mpath: propagate target errors immediately
DM now has more information about the nature of the underlying storage
failure. Path failure is avoided if a request failed due to a target
error. Instead the target error is immediately passed up the stack.
Discard requests that fail due to non-target errors may now be retried.
Errors restricted to the path will be retried or returned if no
paths are available, irregarding the no_path_retry setting.
