LU-10900 osd: wrong assertion in osd_transfer_project

LU-10900 osd: wrong assertion in osd_transfer_project

When project ID feature is not enabled on ldiskfs, the project
ID of any inode should be zero. osd_transfer_project() made
the opposite assertion.

Fixes: LU-10565 osd: move ext4_tranfer_project to osd
