Consistent indentation in shim

[dlespiau]

Well.

It seems the shim has its indentation a bit random, eg.

if(foo)
if (foo)
if ( foo )

We should just stick to one and verify (in CI) that the PR are well formed.

One way to do that would be to decide we're using the kernel coding style, re-indent all the C files with scripts/Lindent from the kernel tree and check every PR with scripts/checkpatch.pl, still from the kernel tree.

Clearly, this is not high priority.
