Fix segfault when copy unaligned struct as aligned

Browse Source 
Because context has one field which is aligned to 64B
(struct ocf_volume cache_volume) the compiler use vmovdqa (aligned)
instead of vmovdqu (unaligned) in reality the address is not 64 aligned,
it ends with 0x8, so we get this segfault.
