[PATCH] unexport open_softirq

Christoph Hellwig:
open_softirq just enables a softirq.  The softirq array is statically
allocated so to add a new one you would have to patch the kernel.  So
there's no point to keep this export at all as any user would have to
patch the enum in include/linux/interrupt.h anyway.
