[PATCH] kconfig: Fix compiler warning

[Eddie Kovsky]

Fixes gcc warning when building linux-next:

In file included from scripts/kconfig/zconf.tab.c:2537:0:
scripts/kconfig/menu.c: In function âget_symbol_strâ:
scripts/kconfig/menu.c:590:18: warning: âjumpâ may be used uninitialized in this function [-Wmaybe-uninitialized]
     jump->offset = strlen(r->s);
                  ^
scripts/kconfig/menu.c:551:19: note: âjumpâ was declared here
  struct jump_key *jump;
                   ^
  HOSTLD  scripts/kconfig/conf

Moved the initialization of struct jump_key *jump outside the first
'if' branch so it can be available throughout the function.

Also uses the preferred pointer syntax for passing the size of a struct.

Tested on next-20141119.
