linux-user: Fix 'clock_nanosleep()' implementation
Implementation of syscall 'clock_nanosleep()' in 'syscall.c' uses
functions 'target_to_host_timespec()' and 'host_to_target_timespec()'
to transfer the value of 'struct timespec' between target and host.
However, the implementation doesn't check whether this conversion
succeeds and thus can return an unaproppriate error instead of 'EFAULT'
that is expected. This was confirmed with the modified LTP test suite
where testcases with bad 'struct timespec' adress for 'clock_nanosleep()'
were added. This modified LTP suite can be found at:
https://github.com/bozutaf/ltp
(Patch with this new test case will be sent to LTP mailing list soon)
