[apparmor] [PATCH] apparmor: put secmark label after secid lookup

[Zygmunt Krynicki]

apparmor_secmark_init() parses a configured secmark label to obtain its
secid.  aa_label_strn_parse() returns a refcounted label, but the success
path kept that reference after copying the secid.

Fixes: ab9f2115081a ("apparmor: Allow filtering based on secmark policy")
