Subject: [PATCH 22/29] afs: Add static attribute to internal functions

When building against a Linux 6.8 kernel, functions that are missing
prototypes or declarations are flagged.

We can add the static attribute to functions that are not referenced
outside of the file that implements them to avoid having these functions
flagged by the compiler.

These functions are flagged due to missing prototypes when building
against a Linux 6.8 kernel (which sets the -Wmissing-declarations and
-Wmissing-prototypes compiler flags as default). Linux 6.8 commit:
 'Makefile.extrawarn: turn on missing-prototypes globally' (0fcb70851f).

When building against a kernel with CONFIG_WERROR=y, the build fails.

There are no functional changes in this commit.
