[PATCH V2 12/17] xprtrdma: Make rpcrdma_ep_destroy() return void

[Chuck Lever <chuck.lever@xxxxxxxxxx>]

Clean up: rpcrdma_ep_destroy() returns a value that is used
only to print a debugging message. rpcrdma_ep_destroy() already
prints debugging messages in all error cases.

Make rpcrdma_ep_destroy() return void instead.
