host_to_target_timespec may return error if target address could not be
locked, but it is ignored.
Propagate return value of host_to_target_timespec to the caller of
clock_gettime.

Could you also update in the same way clock_getres?
There are other syscalls ignoring result of host_to_target_timespec(),
but they are also ignoring result of target_to_host_timespec, but I
don't think the -rc stage is the good moment to fix them all.
Thanks,
Laurent

Ignore this, clock_getres() accepts a NULL pointer.
