[PATCH v2] iwlwifi: Fix missing error code in iwl_pci_probe()

[Jiapeng Chong]

From: chongjiapeng <jiapeng.chong@linux.alibaba.com>

The error code is missing in this code scenario, add the error code
'-EINVAL' to the return value 'ret'.

Eliminate the follow smatch warning:

drivers/net/wireless/intel/iwlwifi/pcie/drv.c:1376 iwl_pci_probe() warn:
missing error code 'ret'.

Fixes: 1f171f4f1437 ("iwlwifi: Add support for getting rf id with blank otp")
