i2c: i801: Improve too small kill wait time in i801_check_post
In my tests terminating a transaction took about 25ms, what is
in line with the chip-internal timeout as described in 5.21.3.2
"Bus Time Out" in [0]. Therefore the 2ms delay is too low.
Instead of a fixed delay let's use i801_wait_intr() here,
this also facilitates the status handling.
This potential issue seems to have been existing forever, but as no
related problem is known, treat it as an improvement.
