Subject[PATCH] kconfig: Fix compiler warning
Fixes gcc warning when building linux-next:

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);
^
scripts/kconfig/menu.c:551:19: note: ‘jump’ 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.
