[V2] common/iavf:replace zero-length arrays with flexible ones

[V2] common/iavf:replace zero-length arrays with flexible ones

[835703180]

From: Shiqi Liu <835703180@qq.com>

        This patch replaces instances of zero-sized arrays i.e. those at
	the end of structures with "[0]" with the more standard syntax of "[]".
	Replacement was done using coccinelle script, with some revert and
        cleanup of whitespace afterwards.
	v2:
	* revise a error with BRACKET_SPACE
