iget: stop CIFS from using iget() and read_inode()
Stop the CIFS filesystem from using iget() and read_inode(). Replace
cifs_read_inode() with cifs_iget(), and call that instead of iget().
cifs_iget() then uses iget_locked() directly and returns a proper error code
instead of an inode in the event of an error.
cifs_read_super() now returns any error incurred when getting the root inode
instead of ENOMEM.
cifs_iget() needs examining. The comment "can not call macro FreeXid here
since in a void func" is no longer true.
