genirq, ARM: Fix boot on ARM platforms
Commit b683de2b3 in linux-next as of 20101014 (genirq: Query
arch for number of early descriptors) seems to have broken
bootup on several ARM boards - my beagleboard gives the
following dump with earlyprintk:
NR_IRQS:402
Unable to handle kernel NULL pointer dereference at virtual
address 00000028 pgd = c0004000
[00000028] *pgd=00000000
Internal error: Oops: 5 [#1]
last sysfs file:

CPU: 0 Not tainted
(2.6.36-rc7-next-20101014-linux-next-20101012+ #40) PC is at
init_IRQ+0x14/0x48 LR is at start_kernel+0x150/0x2c0
[...]
We seem to be using desc->status without assigning desc to
anything. Fix this by adding back the code that was originally
there.
