gpio: just plain warning when nonexisting gpio requested
When trying to export an nonexisting gpio ID, the kernel prints out a
big warning w/ stacktrace, sounding like a huge problem. In fact it's
a pretty normal situation, like file or device not found.
So, just print a more relaxed warning instead.
