[PATCH] irqdesc: Fix missing irq_to_desc export for !CONFIG_SPARSE_IRQ

[PATCH] irqdesc: Fix missing irq_to_desc export for !CONFIG_SPARSE_IRQ

[Paul Gortmaker]

In allmodconfig builds for sparc and any other arch which does
not set CONFIG_SPARSE_IRQ, the following will be seen at modpost:

  CC [M]  lib/cpu-notifier-error-inject.o
  CC [M]  lib/pm-notifier-error-inject.o
ERROR: "irq_to_desc" [drivers/gpio/gpio-mcp23s08.ko] undefined!
make[2]: *** [__modpost] Error 1

This happens because commit 3911ff30f5d1175e2e67e73244405e3492b35c79
("genirq: export handle_edge_irq() and irq_to_desc()") added one
export for it, but there were actually two instances of it, in
an if/else clause for CONFIG_SPARSE_IRQ.  Add the second one.
