show bug in logging: erratic redirection to DLGLOBAL for first invalid category
Add a check to logging_test.c to show a bug: when a logging category value that
is the first out-of-bounds value is passed to the logging system, the internal
map_subsys() fails to redirect to DLGLOBAL due to a flawed conditional. This
results in a too large array index and undefined behavior. A sanitize build
should catch this.
The bug is confirmed by the fact that logging_test.err stays the same
(hopefully) although a logging output should appear from this patch. The test
could as well segfault or anything else, it's a bit of a gamble.
This bug will be fixed along with the expectation in a subsequent patch.
