  dpif: Don't pass in '*meter_id' to meter_set commands.

The original intent of the API appears to be that the underlying DPIF
implementaion would choose a local meter id.  However, neither of the
existing datapath meter implementations (userspace or Linux) implemented
that; they expected a valid meter id to be passed in, otherwise they
returned an error.  This commit follows the existing implementations and
makes the API somewhat cleaner.

  -----------
  dpif-netlink: Probe for broken Linux meter implementations.

Meter support was introduced in Linux 4.15.  In some versions of Linux
4.15, 4.16, and 4.17, there was a bug that never set the id when the
meter was created, so all meters essentially had an id of zero.  This
commit adds a probe to check for that condition and disable meters on
those kernels.
