printenv: Correct out-of-memory condition check. In common/cmd_nvedit.c, en env_print(), the wrong type is used for len. hexport_r() returns -1 on error (like OOM), which is converted to 0xffffffff when put in an unsigned. Said value is obviously bigger then 0, and as a result an uninitialized string is then displayed. Other usages of hexport_r() in the code correctly uses ssize_t to keep its return value.
