merge chain, and current is the only procress, waker_bfqq can be freed from bfq_split_bfqq(). However, the case that waker_bfqq is not in the merge chain is missed, and if the procress reference of waker_bfqq is 0, waker_bfqq can be freed as well. Fix the problem by checking procress reference if waker_bfqq is not in the merge_chain.

Welcome to Mend for GitHub.com (formerly WhiteSource). This is an onboarding PR to help you understand and configure settings before Mend starts scanning your repository for security vulnerabilities.
🚦 Mend for GitHub.com will start scanning your repository only once you merge this Pull Request. To disable Mend for GitHub.com, simply close this Pull Request.
What to Expect
This PR contains a '.whitesource' configuration file which can be customized to your needs. If no changes were applied to this file, Mend for GitHub.com will use the default configuration.
Before merging this PR, Make sure the Issues tab is enabled. Once you merge this PR, Mend for GitHub.com will scan your repository and create a GitHub Issue for every vulnerability detected in your repository.
If you do not want a GitHub Issue to be created for each detected vulnerability, you can edit the '.whitesource' file and set the 'minSeverityLevel' parameter to 'NONE'.
If Mend Remediate Workflow Rules are set on your repository (from the Mend 'Integrate' tab), Mend will also generate a fix Pull Request for relevant vulnerabilities.
❓ Got questions? Check out Mend for GitHub.com docs.
If you need any further assistance then you can also request help here.
