H A Dexec_machdep.ca85cf421 Wed Jan 18 09:30:36 GMT 2023 Andrew Turner <andrew@FreeBSD.org> Reduce an arm64 VFP critical section

In set_fpcontext we only need a critical section around vfp_discard.
The remainder of the code can run without it.

While here add an assert to check the passed in thread is the
current thread as the code already this.
