marker : handle variable `ret` properly in marker_unlink_cbk

Backport of http://review.gluster.org/#/c/12584/

While compiling new source, the following issue got hit :
marker.c: In function 'marker_unlink_cbk':
marker.c:994:29: warning: variable 'ret' set but not used
         int32_t             ret     = 0;
This patch will fix the same.
