Summary: A trivial resource leak fix; free the allocated memory before return.
Test Plan: Code inspection, run command.
I built a simple program that waits for a signal on a kqueue, then ran
that. The standard procstat displays:
```
fbsd-dev% Waiting for SIGTERM...
procstat -a kqueue
PID KQFD FILTER IDENT FLAGS FFLAGS DATA UDATA STATUS
84352 3 SIGNAL 15 C - 0 0x0 -
```
The revised procstat displays:
```
fbsd-dev% sudo LD_LIBRARY_PATH=/usr/obj/usr/home/dab/git/freebsd/src/arm64.aarch64/lib/libutil /usr/obj/usr/home/dab/git/freebsd/src/arm64.aarch64/usr.bin/procstat/procstat -a kqueue
PID KQFD FILTER IDENT FLAGS FFLAGS DATA UDATA STATUS
84352 3 SIGNAL 15 C - 0 0x0 -
fbsd-dev%
```
As expected, the two displays are identical. This doesn't prove that
the leak is gone, but it does prove that the revised command still
operates correctly. I think it can clearly be seen from inspection of
the change that the leak has been remedied.

kern: Introduce RLIMIT_VMM2025-12-17T14:08:31ZBojan Novkovićbnovkov@FreeBSD.org2025-11-07T13:11:03Zurn:sha1:1092ec8b337595ed8d52accf41c6904d75b3689d
This change introduces a new per-UID limit for controlling the
number of vmm instances, in anticipation of unprivileged bhyve.
This allows ut to limit the amount of kernel memory allocated
by the vmm driver and prevent potential memory exhaustion attacks.

manpages: prefer linking to xo_options.7 over xo_parse_args.32025-07-16T18:02:24ZAlan Somersasomers@FreeBSD.org2025-07-16T17:41:31Zurn:sha1:cc61a0793a0e7db8601e5eba1242befb810a5844
Most libxo-enabled utilities link to xo_parse_args.3. But that man page
doesn't actually describe how to format command-line arguments. Rather,
xo_options.7 does. I suspect that these utilities link to the former
because the latter man page did not exist until libxo-0.7.2
(8a6eceff3ce). And newer utilities have probably been copy/pasting the
same text from older ones. But the superior man page does exist now,
so we should link to it instead.
