  odp-util: Initialize nsh_hdr in odp_nsh_hdr_from_attr

For function odp_nsh_hdr_from_attr, paramemter `attr` may not contain
all necessary OVS_NSH_KEY_ATTR_ to fully initialize data of nsh_hdr.
On return, nsh_hdr can contain uninitialized values in its fields.

This patch zeroes out nsh_hdr in the beginning in order to prevent it.
