net: hns3: Fix return of uninitialized variable ret

Browse source

In the unlikely event that rule_cnt is zero the variable ret is
not assigned a value and function hclge_dbg_dump_fd_tcam can end
up returning an unitialized value in ret. Fix this by explicitly
setting ret to zero before the for-loop.

Addresses-Coverity: ("Uninitialized scalar variable")
