powerpc/4xx: Fix setup_kuep() on SMP
On SMP, setup_kuep() is also called from start_secondary() since
commit 86f46f343272 ("powerpc/32s: Initialise KUAP and KUEP in C").
start_secondary() is not an __init function.
Remove the __init marker from setup_kuep() and bail out when
not caller on the first CPU as the work is already done.
