driver core: platform: Emit a warning if a remove callback returned non-zero
The driver core ignores the return value of a bus' remove callback. However
a driver returning an error code is a hint that there is a problem,
probably a driver author who expects that returning e.g. -EBUSY has any
effect.
The right thing to do would be to make struct platform_driver::remove()
return void. With the immense number of platform drivers this is however a
big quest and I hope to prevent at least a few new drivers that return an
error code here.
