Ratheesh Kannoth 50e4921433 octeontx2-pf: Fix page pool frag allocation warning
Since page pool param's "order" is set to 0, will result
in below warn message if interface is configured with higher
rx buffer size.

Steps to reproduce the issue.
1. devlink dev param set pci/0002:04:00.0 name receive_buffer_size \
   value 8196 cmode runtime
2. ifconfig eth0 up
