mm/damon/core: factor out 'damos_quota' private fileds initialization 

The 'struct damos' creation function, 'damon_new_scheme()', does
initialization of private fileds of 'struct damos_quota' in it.  As its
verbose and makes the function unnecessarily long, this commit factors it
out to separate function.
