client: harden og_resp_refresh
Harden refresh response logic. Check for necessary JSON fields inside
the payload.
Check if serial_number is null before calling strlen, prevent ogServer
from a malformed refresh response with missing serial_number.
Refresh uses legacy function actualizaConfiguracion that takes a long
string with the computers configuration (serialno, partitions, disks,
link speed and status). Check for an empty string before executing any
legacy code inside actualizaConfiguracion.
