scsi: zfcp: spin_lock_irqsave() is not nestable

commit e7cb08e894 upstream.

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: aceeffbb59 ("zfcp: trace full payload of all SAN records (req,resp,iels)")
