Jakub Kicinski 4359836129 eth: fbnic: don't build the driver when skb has more than 21 frags ...

Similarly to commit 0e03c643dc ("eth: fbnic: fix s390 build."),
the driver won't build if skb_shared_info has more than 25 frags
assuming a 64B cache line and 21 frags assuming a 128B cache line.

  (512 - 48 -  64) / 16 = 25
  (512 - 48 - 128) / 16 = 21
