[spp] [PATCH 01/17] shared/sec: change prefix of common functions

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

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

Some of common functions are prefixed with `spp_`, but not common
especially for spp_vf siblings. From this patch, change the prefix to
`sppwk_` to be more specific. The meaning of `sppwk` is “SPP worker
(thread)”.

This patch is to refactor struct `spp_command_decode_error` to
`sppwk_parse_err_msg`. It also include refactor of func names, such as
from `set_decode_error()` to `set_parse_error()` for formatting error
message object because it does not decode actually.
