[PATCH] i2c-i801: Fix block transaction poll loops 

i2c-i801: Fix block transaction poll loops

Two of the three poll loops have the poll and sleep swapped,
causing an extra sleep to occur after the polled condition is
fulfilled. In practice, this doubles the amount of sleep time for
every block transaction.
