Fix: Increase Huawei CAN task stack size

the stack size was already increased by Andreas Boehm in df53f34 in
the context of #1144 (SPI port manager). this change aligns the stack
size to a power of two and adds comments. the commit also serves to
place this change more prominently as a fix in the changelogs.
