Subject: [PATCH] [media] dvb-frontends: remove self assignments

These were leftover from:
commit 469ffe083665 ("[media] tda18271c2dd: Remove the CHK_ERROR macro")
and
commit 58d5eaec9f87 ("[media] drxd: Don't use a macro for CHK_ERROR ...")
that programmatically removed the CHK_ERROR macro, which left behind a
few self assignments that Clang warns about.  These instances aren't
errors.
