Current API for bpf_xdp_metadata_rx_hash() returns the raw RSS hash value,
but doesn't provide information on the RSS hash type (part of 6.3-rc).

This patchset proposal is to change the function call signature via adding
a pointer value argument for providing the RSS hash type.

---
V5:
 - Fixes for checkpatch.pl
 - Change function signature for all xmo_rx_hash calls in patch1
