An attempt to establish a connection can always fail and then be
retried. GFP_KERNEL allocation is not necessary here.

Like MR allocation, establishing a connection is always done in a
worker thread. The new GFP flags align with the flags that would
be returned by rpc_task_gfp_mask() in this case.
