[NFS-Ganesha-Devel] Change in ffilz/nfs-ganesha[next]: FSAL_UP: fix op_ctx handling in delegation recall/revoke codepaths

From Jeff Layton <jlayton(a)redhat.com&gt;: Jeff Layton has uploaded this change for review. ( https://review.gerrithub.io/418214 Change subject: FSAL_UP: fix op_ctx handling in delegation recall/revoke codepaths ...................................................................... FSAL_UP: fix op_ctx handling in delegation recall/revoke codepaths delegrecall_task calls dec_state_t_ref at the end of it, which can do a subcall_task call. That requires a valid op_ctx pointer, but we will have already reset op_ctx back to its original value at that point (which may very well be NULL). Fix the code to set up the op_ctx much earlier, on entry into the function and then only switch it back at exit. Also, ensure we clear out the export pointers just before we put the reference to ensure that no subcall will attempt to use them. Also, tighten up some similar op_ctx handling in other delegation recall and revoke handling codepaths.
