ocfs2: Fix a missing credit when deleting from indexed directories.
The ocfs2 directory index updates two blocks when we remove an entry - the dx root and the dx leaf. OCFS2_DELETE_INODE_CREDITS was only accounting for the dx leaf. This shows up when ocfs2_delete_inode() runs out of credits in jbd2_journal_dirty_metadata() at "J_ASSERT_JH(jh, handle->h_buffer_credits > 0);". The test that caught this was running dirop_file_racer from the ocfs2-test suite with a 250-character filename PREFIX. Run on a 512B blocksize, it forces the orphan dir index to grow large enough to trigger. Signed-off-by: Joel Becker <joel.becker@oracle.com>
