[spp] [PATCH 8/8] shared/sec: rename func to convert MAC addr type

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

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

This update is to refactor function for converting MAC address from
string to int64_t type, and revise comments and log messages for
maintenance.

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