libdl object unload debugger delete support is broken

Description

The test dl09.exe crashes on BBB, Zedboard, and RPi2 but runs on arm qemu and psim. The issue is uncovered by the heap protection support in free() where the free block has been touched.

It turns out _rtld_linkmap_delete() list code is broken. The object module's block should not be walked to the end.
