A few drivers optimistically try to support discard, write zeroes and secure erase and disable the features from the I/O completion handler if the hardware can't support them. This disable can't be done using the atomic queue limits API because the I/O completion handlers can't take sleeping locks or freeze the queue. Keep the existing clearing of the relevant field to zero, but replace the old blk_queue_max_* APIs with new disable APIs that force the value to 0.
