tap: fix tap interface not working on Arm issue
The VPP code tries to set all userspace memory in the table via IOCTL
to VHOST_SET_MEM_TABLE. But on aarch64, the userspace address range is
larger (48 bits) than that on x86 (47 bits). Below is an segment from
/proc/[vpp]/maps.

Instead of setting all userspace memory space to vhost-net, will only set
the address space reserved by pmalloc module during initialization.
Type: fix
