Comment # 1 on bug 1189776 from Antonio Feijoo

Confirmed bug in dracut 055 and upstream, regardless of kernel version (5.3,
5.14): it fails if the system has only nvme block devices.

In version 049, dracut installs always a bunch of block device drivers, but in
version 055 it performs several checks to avoid always installing all of them.

Specifically, it is failing the check_block_and_slaves_all function in
dracut-functions.sh 

Working to fix it.
