gpiolib: fix poll(2) support reconfigure on sysfs polarity change

Browse source 
Previously enabled poll(2) support on one edge was never reconfigured when
sysfs polarity change was triggered from kernel, because 'struct device
*dev' shadowed an earlier definition.

Found by sparse, which I should've run much earlier.
