vppinfra: don't call dlmalloc API directly from the code
- it is confusing from end consumer perspective that some thing is somewhere called heap and somewhere mspace - this is base for additional work where heap pointer is not the same thing like mspace Type: improvement Change-Id: I644d5a0de17690d65d164d8cec3c5654571629ef Signed-off-by: Damjan Marion <damarion@cisco.com>
