misc: ad525x_dpot: drop redundant drvdata check

Browse Source 
ad525x_group is registered through the I2C and SPI drivers' dev_groups.
The driver core creates those groups only after probe succeeds and removes
them before invoking the driver's remove callback.  ad_dpot_probe() sets
the driver data before returning successfully, so ad525x_is_visible()
cannot legitimately observe a NULL value.

Drop the redundant check instead of silently hiding every attribute if
the driver lifecycle invariant is ever broken.
