Log Message:
Skip sensors with the same description on the same device at attach time,
if the description of it is not unique, mark the sensor with
ENVSYS_FDUPDESC, return EEXIST and continue.

Also, when changing a description, check that the new description is not
assigned by any other sensor, otherwise return EEXIST.

Note that these restrictions are only per device. Fixes PR kern/36660.
