ext4: Don't use ext4_dec_count() if not needed
The ext4_dec_count() function is only needed when dropping the i_nlink count on inodes which are (or which could be) directories. If we *know* that the inode in question can't possibly be a directory, use drop_nlink or clear_nlink() if we know i_nlink is 1. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
