selinux: Remove redundant assignment to rc
Variable rc is set to '-EINVAL' but this value is never read as it is overwritten or not used later on, hence it is a redundant assignment and can be removed. Cleans up the following clang-analyzer warning: security/selinux/ss/services.c:2103:3: warning: Value stored to 'rc' is never read [clang-analyzer-deadcode.DeadStores]. security/selinux/ss/services.c:2079:2: warning: Value stored to 'rc' is never read [clang-analyzer-deadcode.DeadStores]. security/selinux/ss/services.c:2071:2: warning: Value stored to 'rc' is never read [clang-analyzer-deadcode.DeadStores]. security/selinux/ss/services.c:2062:2: warning: Value stored to 'rc' is never read [clang-analyzer-deadcode.DeadStores]. security/selinux/ss/policydb.c:2592:3: warning: Value stored to 'rc' is never read [clang-analyzer-deadcode.DeadStores].
