Subject: bnxt_en: Do not destroy health reporters during reset
Patch-mainline: v5.18-rc1
Git-commit: f16a9169286691d23906a1bb1c8e07e53113586c
References: bsc#1199736

Health reporter state should be maintained over resets. Previously
reporters were destroyed if the device capabilities changed, but
since none of the reporters depend on capabilities anymore, this
logic should be removed.
