kconfig: Fix warning "‘jump’ may be used uninitialized"
Warning: In file included from scripts/kconfig/zconf.tab.c:2537:0: scripts/kconfig/menu.c: In function ‘get_symbol_str’: scripts/kconfig/menu.c:590:18: warning: ‘jump’ may be used uninitialized in this function [-Wmaybe-uninitialized] jump->offset = strlen(r->s); Simplifies the test logic because (head && local) means (jump != 0) and makes GCC happy when checking if the jump pointer was initialized.
