[PATCH -next] isdn: capi, Use list_for_each_entry() helper

[Jinjie Ruan]

Convert list_for_each() to list_for_each_entry() so that the l
list_head pointer and list_entry() call are no longer needed, which
can reduce a few lines of code. No functional changed.

Probably { } aren't needed now.

## Form letter - net-next-closed

The merge window for v6.6 has begun and therefore net-next is closed
for new drivers, features, code refactoring and optimizations.
We are currently accepting bug fixes only.

Please repost when net-next reopens after Sept 11th.

RFC patches sent for review only are obviously welcome at any time.

See: https://www.kernel.org/doc/html/next/process/maintainer-netdev.html#development-cycle
