[2.6 PATCH] visor: Make URB limit error more visible

[Roger Luethi <rl@hellgate.ch>]

There is only one call to dev_dbg in all of visor.c, the rest is dbg or
dev_err. It already bit us once when warnings didn't turn up in a debug
log. I would argue that a flood of those warnings will warrant report
and inspection anyway (broken app, broken driver, or lame DoS attempt),
so I replaced the dev_dbg with dev_err.
