octeontx2-af: debugsfs: fix pci device refcount leak

Browse source

As comment of pci_get_domain_bus_and_slot() says, it returns
a pci device with refcount increment, when finish using it,
the caller must decrement the reference count by calling
pci_dev_put().

So before returning from rvu_dbg_rvu_pf_cgx_map_display() or
cgx_print_dmac_flt(), pci_dev_put() is called to avoid refcount
leak.

Fixes: dbc52debf9 ("octeontx2-af: Debugfs support for DMAC filters")
Fixes: e2fb373038 ("octeontx2-af: Display CGX, NIX and PF map in debugfs.")
