Geoffrey McRae 5a6f7d4df2 drm/amdkfd: return -ENOTTY for unsupported IOCTLs ...

[ Upstream commit 57af162bfc8c05332a28c4d458d246cc46d2746d ]

Some kfd ioctls may not be available depending on the kernel version the
user is running, as such we need to report -ENOTTY so userland can
determine the cause of the ioctl failure.
