Wolfram Sang e3792886dc i2c: bail out early when RDWR parameters are wrong 
[ Upstream commit 71581562ee ]

The buggy parameters currently get caught later, but emit a noisy WARN.
Userspace should not be able to trigger this, so add similar checks much
earlier. Also avoids some unneeded code paths, of course. Apply kernel
coding stlye to a comment while here.
