virtiofsd: Format imported files to qemu style
Mostly using a set like:
indent -nut -i 4 -nlp -br -cs -ce --no-space-after-function-call-names file
clang-format -style=file -i -- file
clang-tidy -fix-errors -checks=readability-braces-around-statements file
clang-format -style=file -i -- file
With manual cleanups.
The .clang-format used is below.
