step_into(): lose inode argument
make handle_mounts() always fetch it. This is just the first step -
the callers of step_into() will stop trying to calculate the sucker,
etc.
The passed value should be equal to dentry->d_inode in all cases;
in RCU mode - fetched after we'd sampled ->d_seq. Might as well
fetch it here. We do need to validate ->d_seq, which duplicates
the check currently done in lookup_fast(); that duplication will
go away shortly.
After that change handle_mounts() always ignores the initial value of
*inode and always sets it on success.
