fix reiserfs mkdir() breakage
if directory has so many subdirectories that its link count is set to 1 (i.e. "can't tell accurately") and reiserfs_new_inode() fails, we shouldn't decrement the parent's link count in cleanup path; that's what DEC_DIR_INODE_NLINK() is for. As it is, we end up with parent suddenly getting zero i_nlink, with very unpleasant effects. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
