generic-adc-battery: Fix forever loop in gab_remove()

There is a forever loop calling iio_channel_release() because the
"chan < " part of the "chan < ARRAY_SIZE()" is missing.  This is in both
the error handling on probe and also in the remove function.

The other thing is that it's possible for some of the elements of the
adc_bat->channel[chan] array to be an ERR_PTR().  I've changed them to be
NULL instead.  We're still not allowed to pass NULLs to
iio_channel_release() so I've added a check.

Finally, I removed an unused "chan = ARRAY_SIZE(gab_chan_name);" statement
as a small cleanup.
