net: macb: replace min() with umin() calls
Whenever min(a, b) is used with a and b unsigned variables or literals,
`make W=2` complains. Change four min() calls into umin().
stderr extract (GCC 11.2.0, MIPS Codescape):
./include/linux/minmax.h:68:57: warning: comparison is always true due
to limited range of data type [-Wtype-limits]
68 | #define __is_nonneg(ux) statically_true((long long)(ux) >= 0)

drivers/net/ethernet/cadence/macb_main.c:2299:26: note: in expansion of
macro ‘min’
2299 | hdrlen = min(skb_headlen(skb), bp->max_tx_length);
