Additional errors reported by new cppcheck

[jphickey]

Describe the bug
The latest version of cppcheck reports the following errors/concerns in the OSAL source code:

To Reproduce
Execute the following cppcheck command in OSAL (same as what is used in the static analysis workflow "strict" setting):
cppcheck --force --inline-suppr --std=c99 --language=c --enable=warning,performance,portability,style --suppress=variableScope --inconclusive src/bsp/ src/os/

Expected behavior
Should pass cleanly

Ubuntu 22.04 (cppcheck version 2.7)

FYI @jphickey - I'm seeing these new errors in the cppcheck workflow now as well:

src/os/shared/src/osapi-printf.c:269:30: error: syntax error [syntaxError]

                             ^
