xlators/io-stats: Coverity Fix CHECKED_RETURN in resolve_group_name
Issue: Calling "getgrgid_r(gid, &grp, grp_buf, grp_buf_len, &grp_result)"
without checking return value. This library function may fail and return
an error code
Solution: getgrgrid_r returns zero when the operation is successful
and a non-zero error code if there's some error in the operation
Fix: Checked for the return value and redirected to error if the
return value was non-zero
Change-Id: I0d082c6d57c6148b9830bc020140946c06d6f800
BUG: 789278
