Kunwu Chan 0b9817caac rust: optimize rust symbol generation for SeqFile
When build the kernel using the llvm-18.1.3-rust-1.85.0-x86_64
with ARCH=arm64, the following symbols are generated:

$nm vmlinux | grep ' _R'.*SeqFile | rustfilt
ffff8000805b78ac T <kernel::seq_file::SeqFile>::call_printf

This Rust symbol is trivial wrappers around the C functions seq_printf.
It doesn't make sense to go through a trivial wrapper for its functions,
so mark it inline.
