mm: change __remove_pages() to call release_mem_region_adjustable()
Change __remove_pages() to call release_mem_region_adjustable(). This allows a requested memory range to be released from the iomem_resource table even if it does not match exactly to an resource entry but still fits into. The resource entries initialized at bootup usually cover the whole contiguous memory ranges and may not necessarily match with the size of memory hot-delete requests. If release_mem_region_adjustable() failed, __remove_pages() emits a warning message and continues to proceed as it was the case with release_mem_region(). release_mem_region(), which is defined to __release_region(), emits a warning message and returns no error since a void function.
