mqprio: fix potential null pointer dereference on opt
The pointer opt has a null check however before for this check opt is
dereferenced when len is initialized, hence we potentially have a null
pointer deference on opt. Avoid this by checking for a null opt before
dereferencing it.
Detected by CoverityScan, CID#1458234 ("Dereference before null check")
