x86/vdso: Fix lsl operand order
commit e78e5a91456fcecaa2efbb3706572fe043766f4d upstream.
In the __getcpu function, lsl is using the wrong target and destination
registers. Luckily, the compiler tends to choose %eax for both variables,
so it has been working so far.
Fixes: a582c540ac1b ("x86/vdso: Use RDPID in preference to LSL when available")
