[PATCH] add a file_permission helper
A few more callers of permission() just want to check for a different access
pattern on an already open file. This patch adds a wrapper for permission()
that takes a file in preparation of per-mount read-only support and to clean
up the callers a little. The helper is not intended for new code, everything
without the interface set in stone should use vfs_permission()
