spinner: Add to support spinner value %d format.

Summary:
When user set min max as 50, 150 with %d format, then value set as 100.
The spinner value set as '0'
Because the sd->val type is double.
Spinner entry has same problem.

@fix

Test Plan:
Set spinner format as %d.
Check the spinner value.
It's not supported.
