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: 7e773594dada ("sfc: Separate efx_nic memory from net_device memory")
