block: Allow changing max_sectors_kb above the default 512
The patch "block: Use accessor functions for queue limits" (ae03bf6) changed queue_max_sectors_store() to use blk_queue_max_sectors() instead of directly assigning the value. But blk_queue_max_sectors() differs a bit 1. It sets both max_sectors_kb, and max_hw_sectors_kb 2. Never allows one to change max_sectors_kb above BLK_DEF_MAX_SECTORS. If one specifies a value greater then max_hw_sectors is set to that value but max_sectors is set to BLK_DEF_MAX_SECTORS I am not sure whether blk_queue_max_sectors() should be changed, as it seems to be that way for a long time. And there may be callers dependent on that behaviour. This patch simply reverts to the older way of directly assigning the value to max_sectors as it was before.
