[PATCH 2/4] afs: Potential uninitialized variable in afs_extract_data()

From: David Howells

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

Smatch warns that:

fs/afs/rxrpc.c:922 afs_extract_data()
error: uninitialized symbol 'remote_abort'.

Smatch is right that "remote_abort" might be uninitialized when we pass
it to afs_set_call_complete(). I don't know if that function uses the
uninitialized variable. Anyway, the comment for rxrpc_kernel_recv_data(),
says that "*_abort should also be initialised to 0." and this patch does
that.
