Log: Report EBUSY instead of EROFS for attempt of deleting or renaming the root directory of msdosfs mount. The VFS code would handle deletion case itself too, assuming VV_ROOT flag is not lost. The msdosfs_rename() should also note attempt to rename root via doscheckpath() or different mount point check leading to EXDEV. Nonetheless, keep the checks for now. The change is inspired by NetBSD change referenced in PR, but return EBUSY like kern_unlinkat() does.
