[PATCH] IIO: Fix adding more than one iio device eventset

[yauhen.kharuzhy at promwad.com]

From: Yauhen Kharuzhy <yauhen.kharuzhy at promwad.com>

iio_get_new_idr_val() returns new id, but this value was checked as
usual error code.

Also fix typo in sysfs attribute name generation, seems that this name
should be unique.
