Subject: [PATCH] rules: storage - relace blacklist with explicit whitelist

Newly added kernel drivers repeatedly pass our blacklist and
cause trouble for the devices, because they do not expect to
be examined by udev's default rules which include blkid.

This turns the blacklist into a whitelist. Device type which
need support for additional symlinks need to be added to the
whitelist now.

Note, that the by-id, by-path symlinks are only intended for
hotpluggable devices. There is no reason for exotic, or for
statically configured devices to provide them.
