crimson/zns: crimson osd crashes when device size is huge

In reset_device(), if the total number of 512B sectors on the device
is more than INT_MAX then there was a overflow happening, rendering
the nr_sectors as 0, which was causing the failure of the ioctl and
subsequent crash, fix the overflow.
