bnxt_en: Fix bp->fw_health allocation and free logic.
bp->fw_health needs to be allocated for either the firmware initiated reset feature or the driver initiated error recovery feature. The current code is not allocating bp->fw_health for all the necessary cases. This patch corrects the logic to allocate bp->fw_health correctly when needed. If allocation fails, we clear the feature flags. We also add the the missing kfree(bp->fw_health) when the driver is unloaded. If we get an async reset message from the firmware, we also need to make sure that we have a valid bp->fw_health before proceeding.
