[PATCH V2] Staging: wilc1000: Fix build break due to undeclared *wilc and implicit declaration of init_irq

[Punit Vara]

This patch is to the linux_wlan.c file that fixes up break found during
make drivers/staging/wilc1000/linux_wlan.o

Patch add following things to file :
-init_irq declaration
-At preprocessor (!defined WILC_SDIO) to defination of init_irq
-At preprocessor (!defined WILC_SDIO) to defination isr_uh_routine
-removes unnecessary lines to declare *wilc

Patch fixes 702c0e50f and 2c1d05d10 tags.
