[PATCH] libcamera: formatting: Avoid spaces in for loops without expression

[Milan Zamazal]

The clang formatter removes spaces in places of empty expressions in for
loops.  For example, it changes

  for (init; condition; )

to

  for (init; condition;)

libcamera currently uses both the styles and we should use only one of
them for consistency.  Since there is apparently no option to override
the formatter behavior (see
https://clang.llvm.org/docs/ClangFormatStyleOptions.html), let's remove
the extra spaces to make the formatter happy.
