[PATCH 6/9] media: dvb-frontends/helene: Rename priv variable

[Ricardo Ribalda]

Coccinelle triggers a false positive where it thinks that the priv
variable in helene_attach_s and helene_attach is the same variable as
helene_probe. This is due to a bad heuristic in cocci.

We have reported it to cocci, but until/if this is fixed, renaming a
local variable is a good compromise to fix this warning:

./dvb-frontends/helene.c:1049:2-7: WARNING: invalid free of devm_ allocated data
./dvb-frontends/helene.c:1013:2-7: WARNING: invalid free of devm_ allocated data
