Subject: [PATCH] iwlwifi: fix link error without CONFIG_IWLMVM

From: Arnd Bergmann <arnd@...db.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")
Signed-off-by: Arnd Bergmann <arnd@...db.de>
