saner proc_get_inode() calling conventions
commit
d3d009cb965eae7e002ea5badf603ea8f4c34915 upstream.
Make it drop the pde in *all* cases when no new reference to it is
put into an inode - both when an inode had already been set up
(as we were already doing) and when inode allocation has failed.
Makes for simpler logics in callers...
