Subject: [PATCH 02/12] value: Set errno = 0 on non-error path in

 hivex_value_data_cell_offset (RHBZ#1145056).

hivex_value_data_cell_offset may return 0 to indicate that the data is

inline.  This is not an error return, but it was possible for errno to

have a random (non-zero) value along this path.  Explicitly set errno

= 0 on this path.

Thanks: Wei Shi
