  [NVPTX] Correct the condition to print "\t}\n" for DWARF sections

`NVPTXTargetStreamer::changeSection` needs `CurSection` to properly
print "\t}\n" for DWARF sections.

db48f1a1764023f8efeb055e343b967d1eb37d19 added
`MCStreamer::changeSection` before `TS->changeSection`,
making `CurSection == Section` when `getCurrentSectionOnly` switches to
`CurFrag` (626eef5ecf92e98cbfccfa6134e0a760e7592813).

cf311a1131b9aef3e66b2a20ad49cfc77212754b did fix the bug, but the
mechanism is confusing. Fix it using nullable getCurrentSectionOnly().
