There is a mismatch between the passed arguments and the actual
nfp_encode_basic_qdr() function parameter names:
static int nfp_encode_basic_qdr(u64 addr, int dest_island, int cpp_tgt,
int mode, bool addr40, int isld1,
int isld0)
{
...
But "dest_island" and "cpp_tgt" are swapped at every call-site.
For example:
return nfp_encode_basic_qdr(*addr, cpp_tgt, dest_island,
mode, addr40, isld1, isld0);
As a result, nfp_encode_basic_qdr() receives "dest_island" as CPP target
type, which is always NFP_CPP_TARGET_QDR(2) for these calls, and "cpp_tgt"
as the destination island ID, which can accidentally match or be outside
the valid NFP_CPP_TARGET_* types (e.g. '-1' for any destination).
Since code already worked for years, also add extra pr_warn() to error
paths in nfp_encode_basic_qdr() to help identify any potential address
verification failures.
