[PATCH] irq/tracing: Add IRQ name to irq_handler_exit tracepoint

[Wander Lairson Costa <wander@redhat.com>]

The irq_handler_entry tracepoint includes a "name" field, which allows
for easy identification and filtering of specific IRQs. However, the
irq_handler_exit tracepoint lacks this field, making it difficult to
pair corresponding entry and exit events for analysis.

Add the "name" field to irq_handler_exit to enable consistent tracking
and correlation of IRQ entry and exit events.
