iio: accel: sca3000: fix frequency divider condition check

Browse Source 
When setting the sampling frequency, the check for `base_freq / 2` is
followed by an independent `if` statement for `base_freq / 4`. If `val`
equals `base_freq / 2`, the second check fails and falls through to the
`else if (val != base_freq)` branch, returning `-EINVAL` erroneously.

Fix this by chaining the checks with `else if`.
