[PATCH] common/cnxk: fix link cfg for sdp

[Harman Kalra]

Link configure registers are invalid and should not be accessed
for SDP ports. But while on txq release which does SQ flush calls
backpressure disable API which configures these link registers.

Fixes: 58debb813a8d ("common/cnxk: enable TM to listen on Rx pause frames")
