The "p" format specifier already prepends the pointer address with
"0x" when printing.

pthread_condclockwait() can not distinguish between interrupt and timeout,
which cause these API not follow POSIX:
pthread_rwlock_timedrdlock()
pthread_rwlock_timedwrlock()
pthread_condtimedwait()
POSIX:
Upon return from the signal handler the thread resumes waiting for
the condition variable as if it wasnot interrupted
These functions shall not return an error code of [EINTR].
Replacing nxsem_wait() with nxsem_clockwait_uninterruptible() can solve it.

There is a potential problem that can lead to deadlock at
condition wait, if the timeout of watchdog is a very small value
(1 tick ?), the timer interrupt will come before the nxsem_wait()

Summary:
- I found potential bugs in pthread_condclockwait.c
- Actually, sched_unlock() and wd_cancel() were misplaced.
- This commit fixes this issue
Impact:
- pthread_cond_clockwait() only
Testing:
- Tested with ostest with the following configs
- sabre-6quad:nsh, sabre-6quad:smp, sim:ostest
