[PATCH 23.11 1/2] net/nfp: fix firmware abnormal cleanup

[Chaoyong He <chaoyong.he@corigine.com>]

[ upstream commit 3a64e190bcddd51b8e062cf9e78d5f62156e5e0e ]

The logic of 'nfp_fw_setup()' consider both single-pf and multi-pf
firmware, but the abnormal firmware cleanup logic only consider multi-pf
firmware and try to write the heart beat value, which will cause
coredump when using the single-pf firmware.

Fixes: 8ba461d1eecc ("net/nfp: introduce keepalive mechanism for multiple PF")
