[NetLabel]: parse the CIPSO ranged tag on incoming packets

Commit 484b366932be0b73a22c74a82748ca10a721643e added support for the CIPSO
ranged categories tag.  However, it appears that I made a mistake when rebasing
then patch to the latest upstream sources for submission and dropped the part
of the patch that actually parses the tag on incoming packets.  This patch
fixes this mistake by adding the required function call to the
cipso_v4_skbuff_getattr() function.

I've run this patch over the weekend and have not noticed any problems.
