commit b859ebedd1e730bbda69142fca87af4e712649a1 upstream.

Fix `error: expected string literal in 'asm'`.
This happens when compiling an ebpf object file that includes
`net/net_namespace.h` from linux kernel headers.

Include trace:
include/net/net_namespace.h:10
include/linux/workqueue.h:9
include/linux/timer.h:8
include/linux/debugobjects.h:6
include/linux/spinlock.h:90
include/linux/workqueue.h:9
arch/arm64/include/asm/spinlock.h:9
arch/arm64/include/generated/asm/qrwlock.h:1
include/asm-generic/qrwlock.h:14
arch/arm64/include/asm/processor.h:33
arch/arm64/include/asm/kasan.h:9
