commit e416ea62a9166e6075a07a970cc5bf79255d2700 upstream.
Commit 83dcedd5540d ("ksmbd: fix infinite loop in ksmbd_conn_handler_loop()"), changes GFP modifiers passed to kvmalloc(). This cause xfstests generic/551 test to fail. We limit pdu length size according to connection status and maximum number of connections. In the rest, memory allocation of request is limited by credit management. so these flags are no longer needed.
