commit 4abbd2e3c1db671fa1286390f1310aec78386f1d upstream.
In the smc_listen_work(), if smc_listen_prfx_check() failed, the real reason: SMC_CLC_DECL_DIFFPREFIX was dropped, and SMC_CLC_DECL_NOSMCDEV was returned.
Althrough this is also kind of SMC_CLC_DECL_NOSMCDEV, but return the real reason is much friendly for debugging.
