Return ZYPPER_EXIT_INF_CAP_NOT_FOUND when info can't find all caps.

[arozyev]

This change fixes an issue of returning ZYPPER_EXIT_SUCCESS for the situation where 'zypper info non-existent' command fails to find a capatibility with given name (e.g. non-existent). This change will change the 'info' to retrun ZYPPER_EXIT_INF_CAP_NOT_FOUND if any of given capabilities isn't found.
