flowtop: Don't attempt to set sysctl values if initial read fails
Bail out early if we fail to read the current sysctl variable values for net/netfilter/nf_conntrack_acct and net/netfilter/nf_conntrack_timestamp Otherwise we'll not be able restore the previous value on exit/panic. Moreover, if we fail to read the sysctl file, we usually also lack the permissions to write it. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
