net/bnxt: fix device capability reporting

[ upstream commit 47a956a ] 1. Added two functions bnxt_get_tx_port_offloads() and bnxt_get_rx_port_offloads() to report the device tx/rx offload capabilities to the application. 2. This avoids few duplicate code in the driver and make VF-rep capability the same as VF. 3. This will help in selectively reporting offload capabilities based on FW support.
