Subject: [PATCH 23.11] net/nfp: fix port ID meta data use in Rx

From: Long Wu <long.wu@corigine.com>

[ upstream commit ddc84b53f38281ff2c15f7feb7e3a0b556dd92b2 ]

Meta data parsing should be controlled by meta data flag. So use
flag to determine if receive function can use 'port_id' meta data.

Fixes: 580ea0b09a7c ("net/nfp: fix Rx descriptor")
