ocfs2: replace CURRENT_TIME macro
CURRENT_TIME is not y2038 safe. Use y2038 safe ktime_get_real_seconds() here for timestamps. struct heartbeat_block's hb_seq and deletetion time are already 64 bits wide and accommodate times beyond y2038. Also use y2038 safe ktime_get_real_ts64() for on disk inode timestamps. These are also wide enough to accommodate time64_t.
