net/bnxt: restore RSS configuration after reset recovery

During reset recovery, driver is not restoring the VNIC rss hash key.
It's generating a new random hash key which results in unexpected
RSS behavior after recovery. Fixed this by storing the VNIC RSS
configuration to a local struct and then applying the cached value
during the recovery.
