idpf_vport_intr_req_irq() allocates a name for each vector IRQ before
calling request_irq(). On success, the name is released later through
kfree(free_irq()), but when request_irq() fails, the error path only
unwinds the previous vectors and the name for the failed one is leaked.

Free the allocated name on the request_irq() failure path, as done for
the mailbox IRQ in commit 9bff30482c10 ("idpf: Fix mailbox IRQ name leak
on request failure").
