Propagate Error Status to the Shell on fw_printenv Errors
Changed implementation such that fw_printenv returns failure status when one or more specified variables do not exist or when incorrect command syntax is used. This aids scripting fw_printenv such that the script can key of the return status rather than relying on standard error "scraping".
