Subject: Return correct error code when server stack fails.
X-Git-Tag: 1.2.0+RC1~1842
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=594a805abc62cd0f15c3df4ae0c39d091c4e4613;p=platform%2Fupstream%2Fiotivity.git

Return correct error code when server stack fails.

Previously we supressed all stack level errors to OC_STACK_ERROR even
though there are more specific errors available. Also, we always sent
out CA_BAD_REQ causing the client to think it was always its fault.
