Sebastian Ott 659213b899 [S390] cio: disallow driver io for known to be broken paths
When a driver requests to do IO, we will adjust the mask of
paths to be used to exclude varied offline paths.

Drivers trying to do IO solely on paths which are online but some
way defective may lack the information to do proper error handling.

There is no reason to allow the usage of known to be broken paths.
Thus restrict the paths a ccw driver can use for IO to a subset of
the paths cio found usable (this also excludes offline paths).
