[UNIATA] Workaround regression CORE-16078, booting broke on specific Intel Z170

JIRA-user "Illen" reported booting from his Z170 controller worked up to
0.4.12-dev-936-g89aaf0e
and would refuse booting - beginning with uniata commit
0.4.12-dev-937-g
b54613073127f5204660d9e9ab86159fea06b23e

For sure this workaround is just a temporary and no proper solution,
but was confirmed to be working by "Illen".
We have no clear understanding of the real bug yet.
Can be replaced by something better at any time.
It was already committed into 0.4.12, 0.4.13, 0.4.14.
We never had an affected release therefore.

Since no one took care of this bug ever,
the workaround will now be committed to master as well.
