Subject: [PATCH net-next 1/1] nfp: flower: fix size_t compile warning

A recent addition to NFP introduced a function that formats a string with
a size_t variable. This is formatted with %ld which is fine on 64-bit
architectures but produces a compile warning on 32-bit architectures.

Fix this by using the z length modifier.
