rxrpc, afs: Fix missing error pointer check after rxrpc_kernel_lookup_peer()

In the Linux kernel, the following vulnerability has been resolved:

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.
