resource: Pass full extent of empty space to resource_alignf callback
__find_resource_space() calculates the full extent of empty space but only
passes the aligned space to resource_alignf callback. In some situations,
the callback may choose take advantage of the free space before the
requested alignment.
Pass the full extent of the calculated empty space to resource_alignf
callback as an additional parameter.
