sftp_seek: fix

Browse Source 
The new SFTP write code caused a regression as the seek function no
longer worked as it didn't set the write position properly.

It should be noted that seeking is STRONGLY PROHIBITED during upload, as
the upload magic uses two different offset positions and the multiple
outstanding packets etc make them sensitive to change in the midst of
operations.

This functionality was just verified with the new example code
sftp_append. This bug was filed as bug #202:
