smack: Fix a bidirectional UDS connect check typo
The 54e70ec5eb090193b03e69d551fa6771a5a217c4 commit introduced a bidirectional check that should have checked for mutual WRITE access between two labels. Due to a typo subject's OUT label is checked with object's OUT. Should be OUT to IN. Signed-off-by: Zbigniew Jasinski <z.jasinski@samsung.com>
