i2c-tools: only try /dev/i2c/* if opening /dev/i2c-* fails with ENOENT
Trying to access /dev/i2c/* on every error after opening /dev/i2c-* can
mislead users who e.g. don't have root access. Instead of bailing-out
with "permission denied" we currently print "no such file or directory".
Fix it by trying open("/dev/i2c/%d") only if we got ENOENT.
Upstream i2cdetect tries to get any info it can from /sys and /proc even
when invoked by an unprivileged user, but we don't want to add unnecessary
bloat.
