[PATCH v2 2/2] erofs-utils: fsck: add warning for unsupported file types during extraction

[Nithurshen]

When extracting an image using fsck.erofs, if the tool encounters
an unsupported file type (falling into the default case of the
switch statement), it currently skips extraction silently and jumps
straight to verifying the data chunk layout.

Add a warning message to the default case so the user is explicitly
informed that a specific file type was not extracted, rather than
failing silently.
