net/smc: switch smcd_dev_list spinlock to mutex
The similar smc_ib_devices spinlock has been converted to a mutex.
Protecting the smcd_dev_list by a mutex is possible as well. This
patch converts the smcd_dev_list spinlock to a mutex.
Fixes: c6ba7c9ba43d ("net/smc: add base infrastructure for SMC-D and ISM")
