libglusterfs: Add empty and NULL dirents list checks
These checks are needed in case a higher layer intends to
delink the dirent list and passes a NULL pointer to
fop_readdir_cbk_stub for the entries parameter.
Consequently, the gf_dirent_free must guard against an empty list
because the stub that is passed to it mgiht have an empty
dirent list.
