Revert "sd: Fix rw_max for devices that report an optimal xfer size"
This reverts 'commit 9814eb75495b ("sd: Fix rw_max for devices
that report an optimal xfer size")'.
Max sectors limit for request queue(q->limits.max_sectors) is reduced
from 1024 to 16 sectors by above commit and causing performance impact
(reduced by upto 50%). Hence revert the change to fix the performance
issue observed on 8998.
