scsi: zfcp: spin_lock_irqsave() is not nestable
We accidentally overwrite the original saved value of "flags" so that we
can't re-enable IRQs at the end of the function. Presumably this
function is mostly called with IRQs disabled or it would be obvious in
testing.
Fixes: aceeffbb59bb ("zfcp: trace full payload of all SAN records (req,resp,iels)")
