libxlator: Make sure marker_xattr is valid

Problem:
marker_xattr is allocated only when the op_ret is 0. If the final response is
a failure, then the marker time is dict_set with key as NULL. this will be
changed to ref:<address-of-value> by dict_set, so the value won't appear on the
marker-key when the getxattr_cbk is in dht. So dht unwinds with failure EINVAL.

Fix:
Always populate marker_xattr. Fixed dict mem-leak as well.
