Subject: [PATCH 25/27] Fix the logic of obtaining statistics on flow control
 storm suppression

Previously, regardless of the direction specified by -d, FW would return the statistics
of flow control storm suppression in both directions. Now it only returns the statistic
in the specified direction. An example is shown:

hikptool nic_qos -i eth6 -g pfc_storm_para -d rx

before:
PFC STORM Information:
direction: rx
enabled: on
period: 2000ms
pfc threshold: 1000ms
recovery period: 500ms
rx storm suppression count: 14

after:
PFC STORM Information:
direction: rx
enabled: on
period: 2000ms
pfc threshold: 1000ms
recovery period: 500ms
storm count: 14
