idpf_mb_intr_req_irq() allocates the mailbox IRQ name before calling
request_irq(). On success, the name is released later through
kfree(free_irq()), but request_irq() failure returns without freeing it.
Free the allocated name on the request_irq() failure path.
Fixes: 4930fbf419a7 ("idpf: add core init and interrupt request")
