core: fill 'ia_ino' from 'ia_gfid' in 'storage/posix' to preserve same ino number
take the least significant 64bit from gfid and assign it to 'ia_ino', hence for a given file (or directory), the 'ia_ino' number is always same, and we need not worry about the 'itransform' in 'cluster/*' translators. Signed-off-by: Amar Tumballi <amar@gluster.com> Signed-off-by: Anand Avati <avati@gluster.com> BUG: 3042 (inode number should be constant on storage) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=3042
