Bryan Wu 85f6038f21 RAMFS NOMMU: missed POSIX UID/GID inode attribute checking
This bug was caught by LTP testcase fchmod06 on Blackfin platform.

In the manpage of fchmod, "EPERM: The effective UID does not match the
owner of the file, and the process is not privileged (Linux: it does not
have the CAP_FOWNER capability)."

But the ramfs nommu code missed the inode_change_ok POSIX UID/GID
verification. This patch fixed this.
