IB/ehca: Beautify sysfs attribute code and fix compiler warnings
eHCA's sysfs attributes are now being created via sysfs_create_group(), making the process neatly table-driven. The return value is checked, thus fixing a few compiler warnings. Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
