[spp] [PATCH 1/5] shared: add error handling for invalid res UID

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

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

There is no checking for the format of resource UID. It is caused
segmentation fault if invalid resouce UID is given to
parse_resource_uid(). This update is to add the validation and error
handling.
