Linux 4.9 compat: inode_change_ok() renamed setattr_prepare()
In torvalds/linux@31051c8 the inode_change_ok() function was renamed setattr_prepare() and updated to take a dentry ratheri than an inode. Update the code to call the setattr_prepare() and add a wrapper function which call inode_change_ok() for older kernels.
