Sandipan Das 49a6905ab5 i2c-smbus: linux: Fix interface detection 
There are cases where detection of an interface fails due to lack of
permissions when accessing /dev/i2c-*. In some instances, the current
code will perform a double readdir() and skip what should have been
the next interface to be enumerated.

E.g. consider a system with the following configuration

  $ ls -l /sys/bus/i2c/devices
