lib: bitmap: add alignment offset for bitmap_find_next_zero_area()
Add a bitmap_find_next_zero_area_off() function which works like
bitmap_find_next_zero_area() function except it allows an offset to be
specified when alignment is checked. This lets caller request a bit such
that its number plus the offset is aligned according to the mask.
