nfp: fix infinite loop on umapping cleanup
The while loop that performs the dma page unmapping never decrements
index counter f and hence loops forever. Fix this with a pre-decrement
on f.
Detected by CoverityScan, CID#1357309 ("Infinite loop")
Fixes: 4c3523623dc0 ("net: add driver for Netronome NFP4000/NFP6000 NIC VFs")
