[PATCH v3 15/19] hw/scsi/vmw_pvscsi: Remove PVSCSI_COMPAT_DISABLE_PCIE_BIT definition

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

PVSCSI_COMPAT_DISABLE_PCIE_BIT was only used by the
hw_compat_2_5[] array, via the 'x-disable-pcie=on' property.
We removed all machines using that array, lets remove all the
code around PVSCSI_COMPAT_DISABLE_PCIE_BIT, including the now
unused PVSCSIState::compat_flags field.
