Hi-
I'm planning to merge these minor clean-ups with v5.11. Thanks in
advance for any review comments!

Commit c509f15a5801 ("SUNRPC: Split the xdr_buf event class") added
display of the rqst's XID to the svc_xdr_buf_class. However, when
the recvfrom tracepoint fires, rq_xid has yet to be filled in with
the current XID. So it ends up recording the last XID that was
handled by that svc_rqst.

Display all currently possible NFSD_MAY permission flags.
Move and rename show_nf_may with a more generic name because the
NFSD_MAY permission flags are used in other places besides the file
cache.
