odp-util: Fix a bug in parse_odp_push_nsh_action
In this piece of code, 'struct ofpbuf b' should always point to
metadata so that metadata can be filled with values through ofpbuf
operations, like ofpbuf_put_hex and ofpbuf_push_zeros. However,
ofpbuf_push_zeros may change the data pointer of 'struct ofpbuf b'
and therefore, metadata will not contain the expected values.
This patch fixes it by changing ofpbuf_push_zeros to
ofpbuf_put_zeros.
