target-arm/cpu.h: Make cpu_init("nonexistent cpu") return NULL
The macro definition of cpu_init meant that if cpu_arm_init() returned NULL this wouldn't result in cpu_init() itself returning NULL. This had the effect that "-cpu foo" for some unknown CPU name 'foo' would cause ARM targets to segfault rather than generating a useful error message. Fix this by making cpu_init a simple inline function. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Acked-by: Andreas Färber <afaerber@suse.de>
