Revert "gpio: Revert regression in sysfs-gpio (gpiolib.c)"

This reverts commit a292ef5fbbc2cc2323976ac39f79b3921d0decf9.

This commit - while attempting to fix a regression - has caused a number
of other problems. As the fallout from it is more significant than the
initial problem itself, revert it for now before we find a correct
solution.
