[LTP] [COMMITTED] [PATCH] syscalls/getdents01: Fix dirp handling

[Cyril Hrubis]

After previous fix the test still failed with large enough -i parameter,
e.g. -i 10, that was because we incremented the dirp in the run() loop.

This patch fixes that by simply using a different pointer for the loop
that check the buffer content.
