Allocation function return memory that is properly aligned for most data
types, there is no need to manually align the buffer later.
On 64-bit systems this is particularly wrong as struct sta_info should
be 8-byte aligned so this calculation is guaranteed to misalign the
structure. If the architecture requires aligned access, this leads to
an alignment fault and panic.
