[Qemu-devel] [PATCH] scsi: Remove SCSI_BUS macro

[Lei Li <lilei@linux.vnet.ibm.com>]

As step behind Paolo's fix for RHBZ#879657 and according to the current
fix in Commit b5007bc (hmp: do not crash on invalid SCSI hotplug), the
macro SCSI_BUS has already been replaced to object_dynamic_cast which
has been improved when try to cast to NULL value and it is also what
DO_UPCAST macro does. And due to the potential Segmentation risk of
SCSI_BUS, remove this macro.
