Move parsing policy for invalid GUIDs into the Guid class.

        cddl/sbin/zfsd/guid.cc:
        cddl/sbin/zfsd/guid.h:
                o Allow a Guid to be constructed from a string.  The empty
                  string is treated as an invalid Guid.
                o Rename NONE_FLAG to INVALID_GUID to clarify its meaning.
                  The concept of a Guid being "none" only applies in certain
                  contexts like reading a spare label.

        cddl/sbin/zfsd/dev_ctl_event.cc:
                Modify ZfsEvent's constructor  to just use Guid's string
                contructor instead of embedding logic to manually create
                invalid guids when these nvpairs do not exist.

        stable/cddl/sbin/zfsd/vdev.cc:
                Rely on Guid's default constructor creating an invalid
                guid to simplify the handling of pool GUIDs parsed from
                a label.  This also fixes a vdev/pool guid variable mixup
                bug that, due to Guid's default construction, had no ill
                effects.
