net: hns3: modify hclge_restore_fd_entries()'s return type to void

driver inclusion
category: bugfix
bugzilla: NA
CVE: NA

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

When restores rules failed in flow table list, PF driver should delete this
rule in list and go on restore the rest rules. It means that it would never
return other value except "0" in hclge_restore_fd_entries.
So this patch modify the return type to "void".
