NFS: Optimise away the sigmask code in aio/dio reads and writes There are no interruptible waits for asynchronous RPC tasks, so we don't need to wrap calls to rpc_run_task() with an rpc_clnt_sigmask/rpc_clnt_unsigmask pair. Instead we can wrap the wait_for_completion_interruptible() in nfs_direct_wait(). This means that we completely optimise away sigmask setting for the case of non-blocking aio/dio.
