Btrfs-progs: Fix compiler warnings on PPC64
The kernel uses unsigned long long for u64, but PPC64 uses unsigned long by default. This results in compilation warnings such as: print-tree.c:333: warning: format '%llu' expects type 'long long unsigned int', but argument 4 has type 'u64' To fix this, the macro __KERNEL__ needs to be defined before including the file <asm/types.h>. This can be done by defining the macro in "kerncompat.h" and making it the first included file in the relevant header files; this fixes the compiler warnings on PPC64.
