Hao Chen a7678a16c2 drivers/perf: hisi: hns3: Actually use devm_add_action_or_reset()

[ Upstream commit 582c1aeee0a9e73010cf1c4cef338709860deeb0 ]

pci_alloc_irq_vectors() allocates an irq vector. When devm_add_action()
fails, the irq vector is not freed, which leads to a memory leak.

Replace the devm_add_action with devm_add_action_or_reset to ensure
the irq vector can be destroyed when it fails.
