    Fix build failure after f02a5391295e
    
    On main, casting PHYS_TO_DMAP(pa) does not require casting to pt_entry_t
    * because it returns void * after fe3e92e6868d ("PHYS_TO_DMAP: Return a
    void * instead of a vm_offset_t"). That was not MFCed to stable/14 and
    stable/15, thus cast the return value of PHYS_TO_DMAP(pa) to
    pt_entry_t * to fix build failure.
