IIO: 3rd set of fixes for the 6.12 cycle

Usual mixed bag of new issues from this cycle and ancient bugs
recently noticed.

core
- Fix wrong fwnode handle if __fwnode_iio_channel_get_by_name()
  looks at parents of the provider node.
core,backend
- Fix a wrong pointer error check.
gts library
- Fix plausible corner case where the value returned was not set.
- Avoid near infinite loop if the size of the table is 0.
  (neither are an issue for current drivers).
adi,ad4000
- Fix reading of unsigned channels that were returning garbage.
adi,ad7780
- Prevent a division by zero.
adi,ad7923
- Fix buffer overflows in arrays that were not resized when devices
  with more channels were added to the driver.
adi,adxl380
- Check only for negative error codes rather than including the
  positive channel read values in an error check.
invense,common
- Fix an issue where changing the sampling rate to another value and
  back again whilst the FIFO was off would not update things correctly.
kionix,kx022a
- Fix failure to sign extend value read from device.
