Subject: [PATCH] fs/hostfs: Use configured path length

hostfs keeps its own HOSTFS_MAX_PATH wrapper for internal buffers, but
it should not hard-code a path length separate from the system path
configuration.

Define HOSTFS_MAX_PATH from PATH_MAX instead. PATH_MAX is backed by
CONFIG_PATH_MAX, whose default remains 256, so the default hostfs
behavior does not change while configurations that choose a larger path
limit are honored consistently.
