Subject: [PATCH] Btrfs: add missing error code to BTRFS_IOC_INO_LOOKUP handler

If the path doesn't fit in the input buffer, return ENAMETOOLONG
instead of returning with a success code (0) and a partially
filled and right justified buffer.

Also removed useless buffer pointer check outside the while loop.
