[f2fs-dev][PATCH] f2fs: avoid skipping recover_inline_xattr after recover_inline_data

[Chao Yu]

When we recover data of inode in roll-forward procedure, and the inode has both
inline data and inline xattr. We may skip recovering inline xattr if we recover
inline data form node page first.
This patch will fix the problem that we lost inline xattr data in above
scenario.
