Code cleanup.

* subversion/libsvn_wc/update_editor.c
  (do_entry_deletion):
    1) When executing the delete-entry log command SVN_ERR_WC_LEFT_LOCAL_MOD
       errors are caught and cleared.  Don't try to catch it again.
    2) Use svn_wc__write_log() instead of writing it ourselves.
    3) Postpone creation and initialisation of the log_path variable.
    4) parent_path + base_name == full_path, don't do the extra allocation.
    5) Delete unused/useless variables.
