apparmor: fix aa_label_asxprint return check
Clang static analysis reports this issue
label.c:1802:3: warning: 2nd function call argument
is an uninitialized value
pr_info("%s", str);
^~~~~~~~~~~~~~~~~~
str is set from a successful call to aa_label_asxprint(&str, ...)
On failure a negative value is returned, not a -1. So change
the check.
Fixes: f1bd904175e8 ("apparmor: add the base fns() for domain labels")
