nxsem_init(), nxsem_destroy(), nxmutex_init() and nxmutex_destroy()
always return OK, so checking the result only leaves dead code: the
compiler cannot remove it, because these are cross-translation-unit calls
and the nxrmutex_destroy() test is duplicated into every inlined call
site.
Apply the convention already established in commit a47a36bc5b (PR #7473)
to the two definitions which still test the value and to the 54 remaining
call sites. No signature or prototype is changed.
Testing: stm32f103-minimum:nsh builds with -Os without new warnings.
