nfs : avoid invalid usage of `cs` variable in nfs fops
Due to changes from http://review.gluster.org/#/c/12162/ a path variable is added to nfs3_log_common_res() and usually `cs->resolvedloc.path` is passed for that. But in certain fop function `cs` may not filled due error and when it is logged using nfs3_log_common_res() results in a crash. This patch will fix the same.
