Jan Höppner 80443ab629 fdasd: Fix exit status in error cases ...

In error cases, fdasd returns -1 which results in the return value 255.
This is due to the fact that only the low-order 8 bits are used for the
status value. See 2.13 Status Information [1] in the POSIX standard and
the exit() POSIX man page [2] for more details.

Instead of returning -1, use the EXIT_FAILURE constant to indicate
unsuccessful termination properly.
