It makes no sense to even try to decrypt a zero-length chunk of bytes - after
all, the content of the chunk will be the same before and after decryption. :-)

dissect_ieee802154_decrypt() can return NULL for a number of reasons; it should
probably take an argument that points to a status code and fill in that status
code, and dissect_ieee802154_common() should probably do the right thing
depending on that status code (use the status code to put the appropriate
indication in as expert info,  don't even bother dissecting as data if there's
nothing to dissect).
