bugfix patch for SMACK
1. In order to remove any SMACK extended attribute from a file, a user
should have CAP_MAC_ADMIN capability. But user without having this
capability is able to remove SMACK64MMAP security attribute.
2. While validating size and value of smack extended attribute in
smack_inode_setsecurity hook, wrong error code is returned.
