util/nvmutil: reset errno if any write attempted
the way nvmutil is designed, setWord() is only ever called under non-error conditions. however, if one part is valid but the other one isn't, and a command is run that touches both parts, errno is non-zero write writeGbeFile is called in situations where one part is valid, but the other isn't, AND the writes to gbe (in memory) results in a non-change, writeGbeFile is not called; in this situation, errno is not being reset, despite non-error condition this patch fixed the bug, resulting in zero status upon exit under such conditions
