Subject: [PATCH] Revert "SUNRPC: Remove unreachable error condition"

This reverts commit efe57fd58e1cb77f9186152ee12a8aa4ae3348e0.

The assumption that it is impossible to return an ERR pointer from
rpc_run_task() no longer holds due to commit 25cf32ad5dba ("SUNRPC:
Handle allocation failure in rpc_new_task()").

Fixes: 25cf32ad5dba ('SUNRPC: Handle allocation failure in rpc_new_task()')
Fixes: efe57fd58e1c ('SUNRPC: Remove unreachable error condition')
