[PATCH 5.7 103/244] xprtrdma: Fix double-free in rpcrdma_ep_create()

[Greg Kroah-Hartman]

From: Chuck Lever <chuck.lever@xxxxxxxxxx>

[ Upstream commit 85bfd71bc34e20d9fadb745131f6314c36d0f75b ]

In the error paths, there's no need to call kfree(ep) after calling
rpcrdma_ep_put(ep).

Fixes: e28ce90083f0 ("xprtrdma: kmalloc rpcrdma_ep separate from rpcrdma_xprt")
