[PATCH 5.13 053/113] SUNRPC: Fix XPT_BUSY flag leakage in svc_handle_xprt()...

From: Trond Myklebust <redacted>

[ Upstream commit 062b829c52ef4ed5df14f4850fc07651bb7c3b33 ]

If the attempt to reserve a slot fails, we currently leak the XPT_BUSY
flag on the socket. Among other things, this make it impossible to close
the socket.

Fixes: 82011c80b3ec ("SUNRPC: Move svc_xprt_received() call sites")
