btrfs-progs: print-tree: use proper helper for reading offset

Sparse warns

print-tree.c:1261:49: warning: incorrect type in argument 4 (different base types)
print-tree.c:1261:49:    expected unsigned long long [unsigned] [usertype] start
print-tree.c:1261:49:    got restricted __le64 [addressable] [usertype] offset

which means we have to use the helper instead of directly accessing the offset
member. This could print bogus number on bigendian arch.
