Wolfram Sang e088ffa9a0 hwspinlock: propagate errno when registering single lock

hwspin_lock_register_single() always returns 0 despite checking the
result from radix_tree_insert(). Propagate the errno to make sanity
checks in callers of this function actually meaningful.

Fixes: 300bab9770 ("hwspinlock/core: register a bank of hwspinlocks in a single API call")
