[PATCH net-next] net/smc: Remove unused function declarations

[Yue Haibing]

commit f9aab6f2ce57 ("net/smc: immediate freeing in smc_lgr_cleanup_early()")
left behind smc_lgr_schedule_free_work_fast() declaration.
And since commit 349d43127dac ("net/smc: fix kernel panic caused by race of smc_sock")
smc_ib_modify_qp_reset() is not used anymore.
