HNS3: Support debugfs dump fastpath info 

driver inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I99GLS


CVE: NA

--------------------------------------------------------

The current software lacks fastpath debug information,
so this patch adds the debugfs query fastpath information
function. By sending the cmdq command to query fastpath
configuration information and print it.
