[PATCH] common: console: Fix print complete stdio device list

[Patrice Chotard]

In case CONSOLE_MUX and SYS_CONSOLE_IS_IN_ENV are on and
stdin or stdout or stderr are missing in environment, as fallback, get
these either from stdio_devices[std] or stdio_devices[std]->name.

Fixes: 6b343ab38d ("console: Print out complete stdio device list")
