Use dev_err_probe() consistently in the probe path of several ADI IIO
drivers. This simplifies error handling and ensures proper logging of
deferred probes.

Each driver is updated in two patches: first introducing a local
struct device variable to simplify repeated &spi->dev / &client->dev
references, then converting error paths to use dev_err_probe().

Drivers updated:
 - adrf6780
 - admv1014
 - admv1013
 - adf4377
 - ad7293
 - admv8818

Changes in v2:
 - Split each driver update into two patches: one precursor for introducing the
   struct device variable, and one for the dev_err_probe() conversion.(as
   Jonathan Cameron suggested).
 - Dropped ade9000 patch (already accepted).

As I mentioned, use a rule of thumb:

- when devm_ is used in the function, error messages may be converted to
dev_err_probe() as devm_ is supposed to be used only at ->probe() stage

- try to avoid ping-pong type of changes when the same line is modified
2+ times in a row in the same series (there are exceptions, but not here)
