unknown 23061beb73 Bug#22828 _my_b_read() ignores return values for my_seek() calls ...

- Because my_seek actually is capable of returning an error code we should
  exploit that in the best possible way.
- There might be kernel errors or other errors we can't predict and capturing
  the return value of all system calls gives us better understanding of
  possible errors.
