Yoshihisa Abe b5ce1d83a6 Coda: add spin lock to protect accesses to struct coda_inode_info. ...

We mostly need it to protect cached user permissions. The c_flags field
is advisory, reading the wrong value is harmless and in the worst case
we hit a slow path where we have to make an extra upcall to the
userspace cache manager when revalidating a dentry or inode.
