Miaoqian Lin 4245a79003 rxrpc, afs: Fix missing error pointer check after rxrpc_kernel_lookup_peer() 
rxrpc_kernel_lookup_peer() can also return error pointers in addition to
NULL, so just checking for NULL is not sufficient.

Fix this by:

 (1) Changing rxrpc_kernel_lookup_peer() to return -ENOMEM rather than NULL
     on allocation failure.

 (2) Making the callers in afs use IS_ERR() and PTR_ERR() to pass on the
     error code returned.

Fixes: 72904d7b9b ("rxrpc, afs: Allow afs to pin rxrpc_peer objects")
