[spp] [PATCH 1/6] shared/sec: refactor func for getting VLAN ID

[ogawa.yasufumi@lab.ntt.co.jp]

From: Yasufumi Ogawa <ogawa.yasufumi@lab.ntt.co.jp>

Functions for getting VLAN ID or PCAP are named as `get_int_value()`
and `get_uint_value()`. It is not describing the feature and should be
renamed. This update is to change the names to `get_vlan_int_val()` and
`get_vlan_uint_val()`, and revise comments for the functions.

Signed-off-by: Yasufumi Ogawa <ogawa.yasufumi@lab.ntt.co.jp>
