kmemleak: fix sparse warning over overshadowed flags
A secondary irq_save is not required as a locking before it was already disabling irqs. This fixes this sparse warning: mm/kmemleak.c:512:31: warning: symbol 'flags' shadows an earlier one mm/kmemleak.c:448:23: originally declared here Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Acked-by: Pekka Enberg <penberg@cs.helsinki.fi> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
