Subject: [PATCH net] wireless: mediatek: mt7921: fix Wformat build warning

ARRAY_SIZE() is of type size_t, so the format specfier should
be %zu instead of %lu.

Fixes this build warning:

../drivers/net/wireless/mediatek/mt76/mt7921/main.c: In function ‘mt7921_get_et_stats’:
../drivers/net/wireless/mediatek/mt76/mt7921/main.c:1024:26: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 4 has type ‘unsigned int’ [-Wformat=]
   dev_err(dev->mt76.dev, "ei: %d  SSTATS_LEN: %lu",
