ucc_geth: Cleanup repetitive ucc_geth_memclean() calls
Browse files Browse the repository at this point in the history 
No need to call ucc_geth_memclean() so many times, just check for
errors in ucc_geth_open(), and call ucc_geth_stop() in case of errors.

The ucc_geth_stop() may be called anytime and will do the right thing.
