performance/quick-read: Handle unwinding of frame corresponding to read fop properly, while validating cache.

  - there was a possibility of double unwind in case of errors.
  - use a new frame to do open in fd-based fops.
    In case of errors, qr_resume_pending_ops will be called to resume all the
    fops waiting on open. Hence if we use frame corresponding to fop (without
    creating a new one), there is a possibility of frame being freed by the
    time open would've returned to quick-read.
