nfp: don't depend on eth_tbl being available
For very very old generation of the management FW Ethernet port
information table may theoretically not be available. This in
turn will cause the nfp_port structures to not be allocated.
Make sure we don't crash the kernel when there is no eth_tbl:
RIP: 0010:nfp_net_pci_probe+0xf2/0xb40 [nfp]
...
Call Trace:
nfp_pci_probe+0x6de/0xab0 [nfp]
local_pci_probe+0x47/0xa0
work_for_cpu_fn+0x1a/0x30
process_one_work+0x1de/0x3e0
Found while working with broken/development version of management FW.

Fixes: 93da7d9660ee ("nfp: provide nfp_port to of nfp_net_get_mac_addr()")
