powerpc/mm: Refactor the floor/ceiling check in hugetlb range freeing functions
All hugetlb range freeing functions have a verification like the following,
which only differs by the mask used, depending on the page table level.
start &= MASK;
if (start < floor)
return;
if (ceiling) {
ceiling &= MASK;
if (! ceiling)
return;
}
if (end - 1 > ceiling - 1)
return;
Refactor that into a helper function which takes the mask as
an argument, returning true when [start;end[ is not fully
contained inside [floor;ceiling[
