[PATCH v3 0/7] hw/scsi/spapr_vscsi: Fix time bomb buffer overflow

[Philippe Mathieu-Daudé]

This series fixes a possible buffer overflow.

Simples patches first (dissociate the buffer holding DMA
requests with pointer to SRP Information Unit packets) to
clean the issue in the penultimate patch.

v3:
- Fixed typo reported by Greg Kurz
- Addressed Paolo Bonzini review comments as an extra patch
- Added another patch converting a fprintf() call while here

v2:
- Addressed David Gibson review comments

Supersedes: <address@hidden>
