[PATCH] iwlwifi: fix link error without CONFIG_IWLMVM

[PATCH] iwlwifi: fix link error without CONFIG_IWLMVM

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

A runtime check that was introduced recently failed to
check for the matching Kconfig symbol:

ld.lld: error: undefined symbol: iwl_so_trans_cfg
>>> referenced by drv.c
>>>               net/wireless/intel/iwlwifi/pcie/drv.o:(iwl_pci_probe)

Fixes: 930be4e76f26 ("iwlwifi: add support for SnJ with Jf devices")

A sent a similar patch this morning:

https://patchwork.kernel.org/project/linux-wireless/patch/1614236661-20274-1-git-send-email-kvalo@codeaurora.org/

But I forgot to include an Fixes tag, I'll add that to my patch during commit.
