cppcheck: (error) Uninitialized variable
Resolve the following uninitialized variable warnings. In practice
these were unreachable due to the goto. Replacing the goto with a
return resolves the warning and yields more readable code.
[module/icp/algs/modes/ccm.c:892]: (error) Uninitialized variable: ccm_param
[module/icp/algs/modes/ccm.c:893]: (error) Uninitialized variable: ccm_param
[module/icp/algs/modes/gcm.c:564]: (error) Uninitialized variable: gcm_param
[module/icp/algs/modes/gcm.c:565]: (error) Uninitialized variable: gcm_param
[module/icp/algs/modes/gcm.c:599]: (error) Uninitialized variable: gmac_param
[module/icp/algs/modes/gcm.c:600]: (error) Uninitialized variable: gmac_param
