marker: Fix inode value in loc, in setxattr fop

Backport of http://review.gluster.org/15826

On recieving a rename fop, marker_rename() stores the,
oldloc and newloc in its 'local' struct, once the rename
is done, the xtime marker(last updated time) is set on
the file, but sending a setxattr fop. When upcall
receives the setxattr fop, the loc->inode is NULL and
it crashes. The loc->inode can be NULL only in one valid
case, i.e. in rename case where the inode of new loc
can be NULL. Hence, marker should have filled the inode
of the new_loc before issuing a setxattr.
