[PATCH] tools: PCI: Zero-initialize param

[PATCH] tools: PCI: Zero-initialize param

[Shunyong Yang]

The values in param may be random if they are not initialized, which
may cause use_dma flag set even when "-d" option is not provided
in command line. Initializing all members to 0 to solve this.

You can simply write {} instead of {0} - zero is not needed.
