xfrm: use correct size to initialise sp->ovec

[ Upstream commit f1193e915748291fb205a908db33bd3debece6e2 ]

This place should want to initialize array, not a element,
so it should be sizeof(array) instead of sizeof(element)

but now this array only has one element, so no error in
this condition that XFRM_MAX_OFFLOAD_DEPTH is 1
