The workaround of pretending R1B non-data transfers are
data transfers in order for the busy timeout to be respected
by the host controller driver is removed. It wasn't useful
in a long time.
Initially the workaround ensured that R1B commands did not
time out by setting the data timeout to be the command timeout
in commit cb87ea28ed9e ("mmc: core: Add mmc CMD+ACMD passthrough ioctl").
This was moved inside of an if clause with idata->buf_bytes being set
in commit 4d6144de8ba2 ("mmc: core: check for zero length ioctl data").
Since the workaround is now inside of the idata->buf_bytes clause
and intended to fix R1B non-data transfers that do not have buf_bytes
set we can also remove the workaround altogether.
Since there are no data transfer invoking R1B commands this was dead
code.
