Subject: [PATCH 2/2] 9p: avoid double put_trans on parse_opt failure

p9_client_destroy will catch that trans and put it when p9_client_create fails

This was brought up when reviewing an alternative implementation of the
previous patch [1]

Link: https://lkml.kernel.org/r/YzVzjR4Yz3Oo3JS+@codewreck.org [1]
Fixes: 3ff51294a055 ("9p: p9_client_create: use p9_client_destroy on failure")
