[PATCH v1] mfd: dln2: Fix sanity checking for endpoints

[Andy Shevchenko]

While the commit 2b8bd606b1e6 ("mfd: dln2: More sanity checking for endpoints")
tries to harden the sanity checks it made at the same time a regression,
i.e.  mixed in and out endpoints. Obviously it should have been not tested on
real hardware at that time, but unluckily it didn't happen.

So, fix above mentioned typo and make device being enumerated again.
