qapi: Fix argument documentation markup

Member / argument documentation of BlockdevAmendOptionsQcow2,
job-resume, and RDMA_GID_STATUS_CHANGED is parsed as ordinary text due
to missing colon or space before the colon.  The generated
documentation shows these members / arguments as "Not documented".

The fix is obvious: add missing colons, delete extra spaces.
