[PATCH v2 2/2] linux-user, ppc: fix clock_nanosleep() for linux-user-ppc

[Laurent Vivier]

Our safe_clock_nanosleep() returns -1 and updates errno.

We don't need to update the CRF bit in syscall.c because it will
be updated in ppc/cpu_loop.c as the return value is negative.

Notes:
    v2: new patch, remove the PPC part as ret is < 0,
        CRF will be updated in cpu_loop.c
