Revert "dracut-functions: $_x should exist, no need to test." 

This reverts commit b2d225a669.

When there's no /sys/dev/block/$2/slaves/*/dev/ exists, $_x will
be assigned with '/sys/dev/block/$2/slaves/*/dev/', this is invalid.
That commit will lead to some warn msg like:
cat: /sys/dev/block/8:16/slaves/*/dev: No such file or directory
cat: /sys/dev/block/8:32/slaves/*/dev: No such file or directory
