V4L/DVB (12685): dvb-core: check fe->ops.set_frontend return value
Various frontend driver have parameter checks in their set_frontend
functions and return an error if the parameters are not supported,
tda10021 and cx24116 to name two.
The tuning ioctls FE_SET_FRONTEND/FE_SET_PROPERTY only change values
in the property cache and return before set_frontend is called. If a
set_frontend call in software zigzag algorithm fails and the card was
previously locked it will report a lock and the new parameters but is
still tuned to the old transport. This is not detectable from
userspace.
This change checks the return values of fe->ops.set_frontend and
changes the state to the added FESTATE_ERROR for software zigzag.
No lock will be reported to userspace if the State is FESTATE_ERROR.
