SUNRPC: Eliminate side effects from rpc_malloc
Currently rpc_malloc sets req->rq_buffer internally. Make this a more generic interface: return a pointer to the new buffer (or NULL) and make the caller set req->rq_buffer and req->rq_bufsize. This looks much more like kmalloc and eliminates the side effects. To fix a potential deadlock, this patch also replaces GFP_NOFS with GFP_NOWAIT in rpc_malloc. This prevents async RPCs from sleeping outside the RPC's task scheduler while allocating their buffer.
