[PATCH] slab: remove unused align parameter from alloc_percpu

[PATCH] slab: remove unused align parameter from alloc_percpu

__alloc_percpu and alloc_percpu both take an 'align' argument which is
completely ignored.  snmp6_mib_init() in net/ipv6/af_inet6.c attempts to use
it, but it will be ignored.  Therefore, remove the 'align' argument and fixup
the lone caller.
