[PATCH] migration: fix SEEK_CUR offset calculation in qio_channel_block_seek

[Marco Cavenati]

The SEEK_CUR case in qio_channel_block_seek was incorrectly using the
'whence' parameter instead of the 'offset' parameter when calculating the
new position.

Fixes: 65cf200a51ddc6d0a28ecceac30dc892233cddd7 ("migration: introduce a 
QIOChannel impl for BlockDriverState VMState")
