SMACK: Fix the memory leak in smack_cred_prepare() hook
Memory leak in smack_cred_prepare()function.
smack_cred_prepare() hook returns error if there is error in allocating
memory in smk_copy_rules() or smk_copy_relabel() function.
If smack_cred_prepare() function returns error then the calling
function should call smack_cred_free() function for cleanup.
In smack_cred_free() function first credential is extracted and
then all rules are deleted. In smack_cred_prepare() function security
field is assigned in the end when all function return success. But this
function may return before and memory will not be freed.
