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

[PATCH] 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.
