[Qemu-stable] [PATCH 018/156] block-commit: speed is an optional parameter

[Michael Roth]

From: Max Reitz <address@hidden>

As speed is an optional parameter for the QMP block-commit command, it
should be set to 0 if not given (as it is undefined if has_speed is
false), that is, the speed should not be limited.
