ath6kl: fix size_t related warnings

My earlier debug log additions added these warnings when compiling 64 bit
kernels:

  but argument 3 has type 'size_t'

ath6kl/init.c:1192: warning: format '%d' expects type 'int',
  but argument 4 has type 'size_t'
ath6kl/init.c:1236: warning: format '%d' expects type 'int',

ath6kl/init.c:1267: warning: format '%d' expects type 'int',
