[PATCH] jffs2:Fix error paths return value for the function read_unknown

[Nicholas Krause <xerofoify@gmail.com>]

This fixes the error paths in the function read_unknown that return
a value to correctly return -EIO rather then the kernel value for
successful function execution of zero to indicate to this function's
callers that a failure has occurred related to I/O and needs to be
handled by this function's caller.
