arm64 vdso warning: fix non-void function not returning

Browse Source 
arch_setup_vdso() needs to return something even on panic to please gcc.
In theory, flagging panic() with __attribute__((noreturn)) should work
just the same and is a much better solution but for some reason on older
gcc versions setting the flag leads to the weak memset() symbol not
being found !?
