[18/47] hw/i386: Rename default_bus_bypass_iommu

From: Jean-Philippe Brucker <[e-mail]>

Since commit d8fb7d0969d5 ("vl: switch -M parsing to keyval"), machine
parameter definitions cannot use underscores, because keyval_dashify()
transforms them to dashes and the parser doesn't find the parameter.

This affects option default_bus_bypass_iommu which was introduced in the
same release:

$ qemu-system-x86_64 -M q35,default_bus_bypass_iommu=on
qemu-system-x86_64: Property 'pc-q35-6.1-machine.default-bus-bypass-iommu' not found

Rename the parameter to "default-bus-bypass-iommu". Passing
"default_bus_bypass_iommu" is still valid since the underscore are
transformed automatically.

Fixes: c9e96b04fc19 ("hw/i386: Add a default_bus_bypass_iommu pc machine option")
