Grow: fix resize of array component size to > 32bits

If the request --size to --grow an array to is larger
than 32bits, then mdadm may make the wrong choice and
use ioctl instead of setting component_size via sysfs
and the change is ignored.

Instead of using casts to check for a 32-bit overflow,
just check for set bits outside of INT32_MAX.
