ionic: free port_info when probe fails after the port is set up

ionic_probe() allocates the port_info DMA buffer via ionic_setup_one()
-> ionic_port_init(). If probe then fails anywhere after that, it
unwinds through err_out_pci, which never calls ionic_port_reset();
ionic_dev_teardown() and ionic_clear_pci() do not touch port_info, and
so the buffer is leaked. The call was lost when the setup code was
moved into ionic_setup_one().

Since ionic_remove() already frees the port_info DMA buffer with
ionic_port_reset(), call that on the probe error path too. Every path
to err_out_pci runs after ionic_setup_one() succeeded, so the BARs are
still mapped and the firmware gets a PORT_RESET before the buffer is
freed, the same order as in ionic_remove().
