Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject
bogus threaded irq requests") threaded IRQs without a primary handler
need to be requested with IRQF_ONESHOT, otherwise the request will fail.

So pass the IRQF_ONESHOT flag in this case.

The semantic patch that makes this change is available
in scripts/coccinelle/misc/irqf_oneshot.cocci.

The seq_printf return value, because it's frequently misused,
will eventually be converted to void.

     seq_has_overflowed() and make public")

Noticed during a coding review, if we reorganised the checking a
little, we can rid the code of a pointless 'else'.  Whilst looking
for this particular code hunk I noticed another pointless 'else',
which I've subsequently fixed in this patch.

We dereference "desc" before check if it is NULL. I've shifted it
around so we check first before dereferencing.
