The comment for file_cbfs_type() says that it returns 0 for an invalid type. The code appears to check for -1, except that it uses an unsigned variable to store the type. This results in a warning on 64-bit machines.
Adjust it to make the meaning clearer. Continue to handle the -1 case since it may be needed.

Changes in v2: - Bring the 'case 0' from a later patch into this one
