i40e: fix src IP mask checks and memcpy argument names in cloud filter

Fix following issues in the IPv4 and IPv6 cloud filter handling logic in
both the add and delete paths:

- The source-IP mask check incorrectly compares mask.src_ip[0] against
  tcf.dst_ip[0]. Update it to compare against tcf.src_ip[0]. This likely
  goes unnoticed because the check is in an "else if" path that only
  executes when dst_ip is not set, most cloud filter use cases focus on
  destination-IP matching, and the buggy condition can accidentally
  evaluate true in some cases.

- memcpy() for the IPv4 source address incorrectly uses
  ARRAY_SIZE(tcf.dst_ip) instead of ARRAY_SIZE(tcf.src_ip), although
  both arrays are the same size.

- The IPv4 memcpy operations used ARRAY_SIZE(tcf.dst_ip) and ARRAY_SIZE
  (tcf.src_ip), Update these to use sizeof(cfilter->ip.v4.dst_ip) and
  sizeof(cfilter->ip.v4.src_ip) to ensure correct and explicit copy size.

- In the IPv6 delete path, memcmp() uses sizeof(src_ip6) when comparing
  dst_ip6 fields. Replace this with sizeof(dst_ip6) to make the intent
  explicit, even though both fields are struct in6_addr.
