[RESEND,2/2] vfs: replace d_backing_inode() with d_inode() globally

  d_backing_inode() does the same thing with d_inode(), so using
d_inode() to get the inode of dentry instead of d_backing_inode().

Following are the steps to complete search-and-replace:

1) replacing the definition and comment of d_backing_inode() with
   #define d_backing_inode d_inode

2) sed -i -e "s/\<d_backing_inode\>/d_inode/g" $(git grep -l -w "d_backing_inode")
   sed -i -e "/#define d_inode d_inode/d" include/linux/dcache.h
