xfs: kill XLOG_SECTOR_ROUND*()
XLOG_SECTOR_ROUNDUP_BBCOUNT() and XLOG_SECTOR_ROUNDDOWN_BLKNO() are now fairly simple macro translations. Just get rid of them in favor of the round_up() and round_down() macro calls they represent. Also, in spots in xlog_get_bp() and xlog_write_log_records(), round_up() was being called with value 1, which just evaluates to the macro's second argument; so just use that instead. In the latter case, make use of that value, as long as it's already been computed.
