fs: proc: store PDE()->data into inode->i_private
PDE_DATA(inode) is introduced to get user private data and hide the
layout of struct proc_dir_entry. The inode->i_private is used to do the
same thing as well. Save a copy of user private data to inode->
i_private when proc inode is allocated. This means the user also can
get their private data by inode->i_private.
Introduce pde_data() to wrap inode->i_private so that we can remove
PDE_DATA() from fs/proc/generic.c and make PTE_DATE() as a wrapper of
pde_data(). It will be easier if we decide to remove PDE_DATE() in the
future.
