There is need to align to kernel iavf code when setting Tx
queue interrupt vector in messge VIRTCHNL_OP_CONFIG_IRQ_MAP,
if not it maybe cause restart iavf port error in some scenario.

v2:
update git log and add new work around
v3:
update git comment and change fix code as suggestion
v4:
add txq_map in struct avf_info to keep vector mapping info
