nxsem_init(), nxsem_destroy(), nxmutex_init(), nxmutex_destroy(),
nxrmutex_init() and nxrmutex_destroy() cannot fail, so promising a
negated errno value on failure documents an error that is never returned.
The coding standard asks the returned value description to identify all
error values of a function, and there are none, so state that OK is
always returned.
Follows "sched/semaphore: Remove the return value check of
nxsem_init/nxmutex_init", which removed the last checks of these values.
