[PATCH v2] xfsprogs: fix potential memory leak in verify_set_primary_sb()

[Li Zhong]

This patch tries to fix CID 997012, 997013 and 997014 reported by Coverity scan,
as suggested by sekharan.

v2: as Mark pointed out, out in the for loop before also needs list to
be freed. Also remove out lable as it is not referenced any more.
