The root cause is sudo ndctl clear-errors namespace0.2 that is used in RUNTESTS.py -> badblocks.py
It clears not only bad blocks but also devdax attributes.

test: update permissions of DAX devices after clearing bad blocks
d89bab5 
The "sudo ndctl clear-errors" command resets permissions
of DAX block device and its resource files,
because it removes the old files and creates new ones
with default permissions, so their permissions have to be updated.

The "sudo ndctl clear-errors" command resets permissions
of the DAX block device and its resource files
because it removes the old files and creates new ones
with default permissions which interrupts further test execution.
The following commands set permissions which should allow
further test execution to work around this issue.
