Linux 4.9 compat: inode_change_ok() renamed setattr_prepare()

Browse Source 
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.
