block: fix BLKSECTGET ioctl when max_sectors is greater than USHRT_MAX
BLKSECTGET ioctl loads the request queue's max_sectors as unsigned
short value to the argument pointer. So if the max_sector is greater
than USHRT_MAX, the upper 16 bits of that is just discarded.
In such case, USHRT_MAX is more preferable than the lower 16 bits of
max_sectors.
