i965: fix build warning on clang

fixes following warning:
   warning: format specifies type 'long' but the argument has type 'uint64_t' (aka 'unsigned long long')

cast is needed to avoid this change turning in to another warning:
   warning: format specifies type 'unsigned long long' but the argument has type 'uint64_t' (aka 'unsigned long')
