net: ethernet: ti: Fix format specifier in netcp_create_interface()

After commit 3948b05950fd ("net: introduce a config option to tweak
MAX_SKB_FRAGS"), clang warns:

  drivers/net/ethernet/ti/netcp_core.c:2085:4: warning: format specifies type 'long' but the argument has type 'int' [-Wformat]
                          MAX_SKB_FRAGS);
                          ^~~~~~~~~~~~~

  1 warning generated.

Follow the pattern of the rest of the tree by changing the specifier to
'%u' and casting MAX_SKB_FRAGS explicitly to 'unsigned int', which
eliminates the warning.
