env: fix env var autocompletion
commit 560d424b6d7cd4205b062ad95f1b104bd4f8bcc3 "env: re-add support for auto-completion" fell short of its description - the 'used' logic in hmatch_r was reversed - 'used' is 0 if the hash table entry is not used, or -1 if deleted. This patch makes hmatch_r actually match on valid ('used') entries, instead of skipping them and failing to match anything. typing 'printenv tft' and hitting 'tab' now displays valid choices for variable names.
