[PATCH] irqdomain: drop pointless NULL check in virq_debug_show_one

[Rasmus Villemoes]

We've already done data->irq and data->hwirq, and also unconditionally
dereference data in the irq_data_get_irq_chip_data() call.

irqdomain: Drop pointless NULL check in virq_debug_show_one

data has been already derefenced unconditionally, so it's pointless to do a
NULL pointer check on it afterwards. Drop it.
