net: wrong test in inet_ehash_locks_alloc()
In commit 9db66bdcc83749affe61c61eb8ff3cf08f42afec (net: convert TCP/DCCP ehash rwlocks to spinlocks), I forgot to change one occurrence of rwlock_t to spinlock_t I believe sizeof(raw_spinlock_t) might be > 0 on !CONFIG_SMP if CONFIG_DEBUG_SPINLOCK while sizeof(raw_rwlock_t) should be 0 in this case. Fortunatly, CONFIG_DEBUG_SPINLOCK adds fields to both spinlock_t and rwlock_t, but at this might change in the future (being able to debug spinlocks but not rwlocks for example), better to be safe.
