[PATCH v2] btrfs: Cleanup for using BTRFS_SETGET_STACK instead of raw convert
Some codes still use the cpu_to_lexx instead of the
BTRFS_SETGET_STACK_FUNCS declared in ctree.h.
Also added some BTRFS_SETGET_STACK_FUNCS for btrfs_header btrfs_timespec
and other structures.

Changelog v1->v2:
- use the struct member name in the macro of btrfs_file_extent_item.
