SWDEV-365908 - Do not align mem size for IPC

Remove alignment to granularity for IPC handles as ROCr has a patch that
will internally validate pointer sizes against requested size during
allocation instead of size aligned to page size. This patch is needed
together with this patch from ROCr:
f8a42a3a:Use user requested size for memory fragments
