rxrpc: checking for IS_ERR() instead of NULL
rxrpc_lookup_peer_rcu() and rxrpc_lookup_peer() return NULL on error, never error pointers, so IS_ERR() can't be used. Fix three callers of those functions. Fixes: be6e6707f6ee ('rxrpc: Rework peer object handling to use hash table and RCU') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David Howells <dhowells@redhat.com>
