From: Arnd Bergmann <arnd@arndb.de>

The structleak plugin causes the stack frame size to grow immensely:

lib/bitfield_kunit.c: In function 'test_bitfields_constants':
lib/bitfield_kunit.c:93:1: error: the frame size of 7440 bytes is larger than 2048 \
bytes [-Werror=frame-larger-than=]

Turn it off in this file.
