selinux: fix double free
commit 65de50969a77509452ae590e9449b70a22b923bb upstream.
Clang's static analysis tool reports these double free memory errors.
security/selinux/ss/services.c:2987:4: warning: Attempt to free released memory [unix.Malloc]
kfree(bnames[i]);
^~~~~~~~~~~~~~~~
security/selinux/ss/services.c:2990:2: warning: Attempt to free released memory [unix.Malloc]
kfree(bvalues);
^~~~~~~~~~~~~~
So improve the security_get_bools error handling by freeing these variables
and setting their return pointers to NULL and the return len to 0
