9p: Enable symlink caching in page cache

Browse source

Currently, when cache=loose is enabled, file reads are cached in the
page cache, but symlink reads are not. This patch allows the results
of p9_client_readlink() to be stored in the page cache, eliminating
the need for repeated 9P transactions on subsequent symlink accesses.

This change improves performance for workloads that involve frequent
symlink resolution.
