igc: Allow hot-swapping XDP program

Browse source

Currently, the driver would always close and reopen the network interface
when setting/removing the XDP program, regardless of the presence of XDP
resources. This could cause unnecessary disruptions.

To avoid this, introduces a check to determine if there is a need to
close and reopen the interface, allowing for seamless hot-swapping of
XDP programs.
