Jeff King 30a569d1a7 Revert "write-index: check and warn when worktree crosses a filesystem boundary" ...

This reverts commit 52b98a7d2f.

The goal of that commit was to warn users early when their
worktree crossed filesystem boundaries. It worked by
comparing the st_dev stat information in the index, and
warning when we had more than one device.

However, the stat information may come from multiple runs,
and the st_dev field is not necessarily stable. In
particular, st_dev will change on Linux across reboots.
Index entries from the previous reboot will appear to come
from a different device, triggering a false positive.

Since this message is really only an early warning for
people who will be bit by the new
GIT_DISCOVERY_ACROSS_FILESYSTEM behavior, and because they
will get an actual error later on (when we can't find their
cross-filesystem .git directory), we can just scrap the
early warning.
