  From: Simon Glass <simon.glass@canonical.com>

Move several inode-related stubs to their canonical Linux header
locations:

- inode_needs_sync and is_bad_inode to linux/fs.h
- in_group_p to linux/cred.h

These are standard Linux kernel interfaces that belong in their
respective headers rather than in the ext4l compatibility layer.
