SYSLINK: ipc - fix for listmp_sharedmemory_destroy

This patch fixes for the listmp element pointer corruption in
listmp_sharedmemory_destroy function. The corruption is caused
by usage of the linux kernel list macros within the
listmp_sharedmemory_delete function.

The patch also assigns SysM3 as the default remote owner processor for
lists being opened.
