[PATCH 11/11] bug_fl(): add missing `va_end()` call

From: Johannes Schindelin <redacted>

According to the manual:

	Each invocation of va_copy() must be matched by a corresponding
	invocation of va_end() in the  same function.

Note: There is another instance of `va_copy()` in `usage.c` that is
missing a `va_end()` call, in `BUG_vfl()`. It does not matter there,
though, because that function either `exit()`s or `abort()`s, anyway.

Reported by Coverity.
