cifs: convert cifs_get_inode_info and non-posix readdir to use cifs_iget
cifs: convert cifs_get_inode_info and non-posix readdir to use cifs_iget Rather than allocating an inode and filling it out, have cifs_get_inode_info fill out a cifs_fattr and call cifs_iget. This means a pretty hefty reorganization of cifs_get_inode_info. For the readdir codepath, add a couple of new functions for filling out cifs_fattr's from different FindFile response infolevels. Finally, remove cifs_new_inode since there are no more callers.
