Subject: [PATCH] [spinel] abort host after receiving unexpected reset from RCP
 (#8909)

Some platforms, such as Android and CastOS, can monitor program crash.
And they can upload the crash dump to the crash server for developers
to analyze the crash reason.

This commit aborts the host after receiving a unexpected reset to
trigger platforms to upload the crash dump.
