bnxt_en: Send FUNC_RESOURCE_QCAPS command in bnxt_resume()

Browse Source 
After driver unregister, firmware is erasing the information that
driver supports new resource management. Send FUNC_RESOURCE_QCAPS
command to inform the firmware that driver supports new resource
management while resuming from hibernation.  Otherwise, we fallback
to the older resource allocation scheme.

Also, move driver register after sending FUNC_RESOURCE_QCAPS command
to be consistent with the normal initialization sequence.
