o Add MOUSE_PS2_TAP into syncmask[0] correctly when we're built with
   PSM_CONFIG_FORCETAP.  The previous code from revision 1.56 attempted
   to do this but updated the a mask variable that would be clobbered later.
o  If syncmask[1] hasn't yet been set when ioctl(MOUSE_GETMODE) is called,
   zero syncmask[0] and syncmask[1] so that sync validation is effectively
   disabled in userland applications and moused doesn't misbehave.  The
   psm driver performs sync validation so there is no loss in functionality
   in clearing the sync mask.
o  If PSM_NEED_SYNCBITS is set, setup syncmask[1], even if it's already
   correct.  This prevents the PSM_NEED_SYNCBITS bit from being left on
   after a re-initialisation and erroneously causing a subsequent
   out-of-sync packet to mis-set syncmask[1].
