resource: Handle simple alignment inside __find_resource_space()

allocate_resource() accepts ->alignf() callback to perform custom alignment
beyond constraint->align. If alignf is NULL, simple_align_resource() is
used which only returns avail->start (no change).

Using avail->start directly is natural and can be done with a conditional
in __find_resource_space() instead which avoids unnecessarily using
callback. It makes the code inside __find_resource_space() more obvious and
removes the need for the caller to provide constraint->alignf
unnecessarily.

This is preparation for exporting find_resource_space().
