SYSLINK:proc-fix in ducati enabler hw mmu module

This fixes the bug in hw mmu module where the
table entries that has memory segment information
was getting corrupted after first run. This bug
causes the consecutive runs to fail.
This patch also fixes the memory leak associated with
not calling iounmap and fixes a compile warning as one
of the function is unused.
