PATCH: zftp: fix some mistakes

[Mikael Magnusson <mikachu@xxxxxxxxx>]

The freesession function randomly clearing the current session instead
of the passed section is probably not great.

The h_errno definition is repeated just above identically, which I would
assume is a compile time error for anyone who has USE_LOCAL_H_ERRNO set.
