[PATCH] pwclient: Don't display header for people who have no patches

[Michael Ellerman]

When searching for patches by a person, currently pwclient prints the
header even for people who have no patches. This makes the output noiser
than it needs to be, eg:

  $ pwclient list -w foo
  Patches submitted by Ley Foon Tan <lftan at altera.com>:

  --      -----        ----

  Patches submitted by ainiaa2k9VG ainiaa5f8VG <camisetasfootballs at gmail.com>:
  ID      State        Name
  --      -----        ----

This commit changes the logic to only display the header info if there
are patches to display. It also tracks if there were any patches found
at all, if not it prints:

  $ pwclient list -w foo
  Note: No patches found for anyone matching *foo*
