3rd set of IIO fixes for the 4.0 cycle.

* A double free occured on an error path in due to an event registration issue.
  The fix is the minimal change rather than possibly reworking this area of
  the core to give a more elegant solution (future work).
* A number of drivers were directly accessing indio_dev->buffer->scan_mask
  to identify the currently enabled channel set.  This may not be correct
  if we have additional clients on the push interface.  The correct option
  is indio_dev->active_scan_mask. This is fixed.
* bmc150 had incorrectly specified sampling frequency (a datasheet confusion
  as they are specified in terms of bandwith - e.g. half the sampling
  frequency).
* hmc5843 wasn't setting it's name and hence the name attribute was
  returning an empty string.
* inv_mpu6050 wasn't clearing the locally held timestamp buffer when the
  hardware fifo was reset. Also an inconsistency existed in the interface
  for the scale of the channels.  Magic numbers were written but real ones
  were used for the reads.  Now uses real numbers (i.e. not array indexes)
  for both.
* fix a missing dependency in the dummy driver. Previously shielded from
  the autobuilders by an earlier build error.
