Fixed coverity issues

(cherry picked from commit 4ba3aae2ea0290ca012623083e13625e08a9dde5)
Cosmetic fixed. three in total. 1. Only run hv_kvp_daemon if it exists. 2. add the -f argument to the rm to make is silent if it doesn't exist. 3. by using log_action_msg instead of log_action_begin_msg the screen output looks way better.
