Subject: [PATCH] fs: doc: describe 'pinned' parameter in do_lock_mount()

The kernel-doc comment for do_lock_mount() was missing a description
for the 'pinned' parameter:

  Warning: fs/namespace.c:2772 function parameter 'pinned' not described
  in 'do_lock_mount'

This patch adds a short description:

  @pinned: receives the pinned mountpoint

to fix the warning and improve documentation clarity.
