sfc: Fix an error handling path in efx_pci_probe()

If an error occurs after the first kzalloc() the corresponding memory
allocation is never freed.

Add the missing kfree() in the error handling path, as already done in the
remove() function.

Fixes: 7e773594da ("sfc: Separate efx_nic memory from net_device memory")
