77341f61ba ctdb-scripts: Avoid shellcheck warning SC2002 (useless cat)
SC2002: Useless cat. Consider 'cmd < file | ..' or 'cmd file | ..' instead.

0ca00267cd ctdb-scripts: Avoid shellcheck warning SC1004 (backslash in quotes)
SC1004: You don't break lines with \ in single quotes, it results in
literal backslash-linefeed.

These don't hurt, since awk can cope with the continuations.  However,
they don't add anything.

b208ae73d1 ctdb-scripts: Avoid shellcheck warning SC2154 (unassigned variables)
SC2154: VAR is referenced but not assigned.

Change ctdb_setup_service_state_dir(), ctdb_get_pnn() and
ctdb_get_ip_address() to print the value so it can be assigned to a
variable.  The performance gain from avoiding the sub-shells when
calling these functions is close to zero.
