[PATCH] osmo-pcu[master]: Assert valid CS

[Max]

Hello Jenkins Builder,

I'd like you to reexamine a change.  Please visit

    https://gerrit.osmocom.org/3893

to look at the new patch set (#2).

Assert valid CS

The coding scheme converted to number make sense only if it's
valid. This is implicitly assumed by the code using this conversion as
non-zero value. Make those assumptions explicit with OSMO_ASSERT().
