performance/quick-read: access glusterfs_ctx from xlator instead of using glusterfs_get_ctx

- since glusterfs_get_ctx gets the global context pointer, there can be
    problems in a multithreaded application running on libglusterfsclient
    doing multiple glusterfs_inits. Hence use context specific to the
    current xlator tree stored in each xlator object.
