msgviewer: fix segfault when closing viewer
There is a race between PartViewer.Cleanup and PartViewer.Draw. pv.term
may be not nil in Draw and Cleanup() may set it to nil before
pv.term.Draw() is called, causing an invalid memory access:
[signal SIGSEGV: segmentation violation code=0x1 addr=0x29 pc=0x9413b8]
git.sr.ht/~rjarry/aerc/widgets.(*Terminal).Draw(0x0?, 0x0?)
git.sr.ht/~rjarry/aerc/widgets/terminal.go:97 +0x18
git.sr.ht/~rjarry/aerc/widgets.(*PartViewer).Draw(0xc00012a540, 0xc0026ea690)
git.sr.ht/~rjarry/aerc/widgets/msgviewer.go:862 +0x2fd
There is no need to reset term to nil.
Fixes: 77f69501d648 ("msgviewer: properly close embedded terminal")
