[XFS] clean up some xfs_log_priv.h macros
- the various assign lsn macros are replaced by a single inline, xlog_assign_lsn, which is equivalent to ASSIGN_ANY_LSN_HOST except for a more sane calling convention. ASSIGN_LSN_DISK is replaced by xlog_assign_lsn and a manual bytespap, and ASSIGN_LSN by the same, except we pass the cycle and block arguments explicitly instead of a log paramter. The latter two variants only had 2, respectively one user anyway. - the GET_CYCLE is replaced by a xlog_get_cycle inline with exactly the same calling conventions. - GET_CLIENT_ID is replaced by xlog_get_client_id which leaves away the unused arch argument. Instead of conditional defintions depending on host endianess we now do an unconditional swap and shift then, which generates equal code. - the unused XLOG_SET macro is removed.
